Flexim Ultrasonic Flow Meter Getting Started

welcome to the flexing training series this is video 1 a hands-on training on how to program and install the flexing f6o one portable meter congratulations on your F 601 portable flow meter purchase from flex them the F 601 has been packaged in a very nice robust pelican carry case has been smartly laid out you have your power cord tape measure your download software here’s your data package which has your manual and pipe charts and other important information full calibration on the meter top panel pulls out it contains your meter your transducers a coiled around here it has enough size to fit at least two sides transducers I’m carrying here the M transducer and the Q transducer what the M size transducer you can cover from a roughly four inch pipes to essentially the largest size pipe that you can still get a signal through which depends someone on the pipe conditions but you can easily do a 40 inch pipe a chilled water type application or most liquid applications that are not introducing an extra level of challenge like a slurry or old pipes that may have a lot of scaling build up with your Q sized transducer you can cover from half inch to four inch pipes and that can be stretched up to slightly larger diameters 6 8 10 inch depending on the condition again of the pipe here we have some pretty good pipe stainless pipe the queue size transducers would work quite well fifths were 12 inch happens to be a six inch the Q sizes would work well on this because you’d still get a strong signal in the bottom part of the panel it contains all the mounting hardware chains for mounting the portable transducers coupling grease temperature sensor if you have the temperature accessory and you’re going to be doing either just standalone temperature and maybe BTU measurements okay so we’re just going to get right into it we’ll take the Flex and portable meter out of here it’s been very smartly designed for handling it has a retractable arm that you can set it up on a table you can set it on the pipe sometimes like this it also comes with a pipe strap and we can put the pipe strap on and snap it to the pipe strap one of the things that we try to get people to recognize is that this is really quite quite an easy media to program I expect that within five or ten minutes time on this video we’ll have the meter up and running and you’ll see how easy it is to operate your new F 601 portable okay so we start off we’ll hit the on key we’ll see the first two flexsim introductory screen come up gives the Flex and part number and serial number of the meter now we’re going to bait the base menu of the fleximeter there’s four key parameters here the first one left is PA auto stands for parameter M EA stands for measure opt for options and SF for special functions now you see you have arrow keys left right the number four key has a left arrow sign on it the six keys right the eight key is an up arrow and the the two keys is down out so I can I can move along the menu screen with the arrow keys so if I go left here you’ll see that the arrows are now over the parameters part of the menu that’s where we’ll stop typically the thing to remember is that the programming starts from the left and proceeds to the right okay so we pressed our our key over and now we see that the arrows are on the parameters part of the menu and the thing to remember here quite simple is that we’re going to do our programming from left to right so we’re going to start at parameters parameters is where we’re going to enter in the pipe information information about the pipe and liquid and the measure screen is where we’re going to go to take our measurement some of these other items here options and special functions are screens where we will be choosing additional items such as if we want to decide that we prefer to read it Li there is instead of gallons if we want to turn on our data logger we want to set our clock all these things are done in the options and special functions part of the menu the main entries are done for simple

flow measurements are done in parameters and measure okay so we install off add parameters here we’re going to hit the enter key and the first question is asked is channel a do we want to program the channel a you’ll see a little if you can see this little arrow prompt here anytime you see that that means if I press an up or down arrow it will toggle me through other choices and the other choices I’m looking at is a channel B Channel Y and channel Z now this meter is a two channel meter well that all the f6o one portal is a two channel capable then we have a channel a and a channel B which means we can we can run flow measurement tests on two different pipes simultaneously one a channel a one a channel B we can do additional things like summing and subtracting and that’s where we would use the the y and z channel those are calculation channels where we could say I want the y channel to be the a channel minus the beach out okay so we’re going to choose channel a here and one of the things we also want to do before we start the programming is we want to connect up all transducer because the meter needs to recognize the transducer and know which transducer we’re doing all measurement with now we have to we have to know a little bit something about which transducer to to select and again the there are two basic sizes of transducers the EM size and you’ll see it you’ll see it on the top of the transducer this one says M to n 7and and the M size is a good four inch up you can stretch it down to even down to two inches that’s the means of size range is four inches and up the queue size here smaller size transducer is good from half inch up to four inches and that can be stretched out a little further from four inches okay so you have to know which transducer based on the pipe size you’re measuring which transducer you need to pull out of the suitcase so now we’re going to plug this transducer in so that the meter has a chance to recognize which transducer we’re working with there’s a red dot on this lemo connector here and on the top of the connector you’ll see a red dot as well and we line up these two dots plug it in and I don’t know if you were able to see that or not the camera was zoomed in but when we plugged it in it said detected transducer on Channel and I’ll do that again okay and you see it’s this clamp on detected on channel a so it has an automatic recognition of the transducer inside this lemo connector here there’s a micro what we call sense prompt chip and that sense prompt chip contains all the information about the transducer as well as its calibration information and and and what size transducer it is so it both installs the calibration data for that transducer and tells the me to what transducer you are using so that’s one of the things that you can’t make a mistake on when you’re programming the meter as well so back to the parameters menu we hit the enter key parameter for channel a the first thing it asks now is what is the outer diameter of the pipe now you can see that we’ve already cheated on this one because this is a six-inch pot but I’m going to repro enter that pipe dimension in for you we just punch in 6.6 to 5 and press Enter then we punch in the pipe wall thickness this happens to be a 0.26 old pipe wall now if I could just talk a little bit about pipe dimensions you’ll find out the inside panel of the meter a pipe shot and there will be pipe shots for steel pipes stainless pipes Hastelloy ductile iron copper etc now this is one place where the user can make a mistake and and so we want to spend just a little bit of time on this now this is a 6-inch pipe nominally if you look at the nominal size for a 6-inch pipe it says OD 6.6 to 5 and if this were a standard wall pipe or a schedule 40 pipe the the wall thickness is point 2 800 now I just want to emphasize that because one of the common mistakes that people make when they’re programming the meter is they’ll put in 6 inches as the OD so make sure you’re putting in the true outside diameter of the pipe one thing

you probably want to do is to just verify what that is take your tape measure wrap the tape measure around the pipe you’ve got the circumference divided by 3.14 you’ll get you outside diameter and I’ve found through a lot of years of doing this that these pipe shots are pretty true so if you measure six point six to eight and the outside diameter says six point six to five I will tend to put in the the nominal the outside diameter that uh that’s referenced on the pipe shot because it’s probably more accurate than than the measurement that you just took what a tape measure there’s also pipe trucks in here for copper pipe you’ll sometimes come across like a ductile iron pipe or cast pipe and you’re not sure if it’s a common steel or cast by measuring the outside diameter and finding out where it fits on the pipe shot that’ll help you determine do I have a carbon steel pipe or do I have a cast-iron pipe because cast iron has different nominal dimensions than carbon steel stainless happens to be the same nominal dimensions as as call them steel okay so measured I’ve installed the the pipe outside diameter I’ve installed the wall thickness and the next question the the media asked me is what’s the pipe material and here we selected stainless you’ll see if I I have the little arrow prompt here up down our prompt so if I scroll through you’ll see that there’s quite a list of virtually any pipe that you’re going to come across you’ll find in our list there’s the stainless again okay so will will stop on the stainless and hit enter now if the material or the entry that you’re looking for is already present you just hit the enter key and that moves you to the next question lining it’s asking about an internal liner some pipes have internal liners a common would be ductile iron pipes that have cement lines internal cement liners if you choose yes it will ask you what the material type is of the liner and then they’ll ask you to enter in the thickness of the liner again if you look at the pipe shots on you’ll find on the doctor line you’ll find also typical liner thicknesses okay we’ll say no on the liner the next thing is pipe roughness now the meter installs a default value for pipe roughness that’s internal roughness and you’re best to not think too much about that just leave the meters of value alone next question it asks is what is your liquid medium here you’ll see it’s got water and I’ll just run real quick through a lot of the choices hydrofluoric caustic glycol certain glycol percents which you’ll see a lot in the HVAC type applications we have some mobile therms where you’ll see in very high temperature applications where we tend to use our wave injector and go up to 700 degrees and continue around ethanol methanol until we find water again diesel crude oil juice milk beer of course because it’s a German product and other medium and back to water okay so now we got water we’re going to hit enter and it asks you for the temperature of the water I can feel the temperature of the pipe feels like it’s about 70 degrees that’s generally good enough because it’s not doing a calculation based on a volume is is not a temperature determinant so if we were doing a mass the me would have to know what the temperature of the liquid is but for volume it doesn’t really need need to know that the reason why it’s asking what the temperature is is because it has some impact on the angle that the beam enters the the liquid and that has impact on what the what optimal spacing will be so but just a rough estimate is good enough let’s say I put in 70 degrees okay and we’re done with what we had to tell the media about the of the application parameters now we go to the measurement screen press enter now we’ve got measurement channels AV y&z there you’ll see there’s a little check mark next to the a channel and the other channels are deactivated right now if I wanted to activate another channel I would scroll over to it activate it with an up/down arrow deactivate it again back to the a channel hit enter it asks a measurement point number but not only ask this question if we have our

internal data logger turned on so it happens to be that this term this data logger is turned on right now and this measurement point number is just an identifier for what the what the data set is now that we’re measuring and we can choose to put in a number or we can choose to put in our alpha Marek name or number okay I’ll just I’ll just leave the – and now I’ll hit enter now now it’s asking number of sound paths now typically we recommend starting with to sound paths now to sound paths is when our transducers are on the same side of the pipe one sends a sound beam out it echoes off the fallpipe wall and comes back to the receiver and that’s – it’s taking two round trips through through the pipe and that’s why it’s called – sound path one sound path would be where the other transducer is on the opposite side of the pipe let me show it to you like this so you can see it that would be one sound pip you typically don’t want to mount on the top and bottom of the pipe because if there’s any air in the pipe it tends to cling to the top of the pipe right so we’d be something like this now we recommend starting at to sound paths it a it makes mounting the transducers and spacing and measuring the spacing distance much easier and be going through the liquid twice provides better averaging of the of the flow profile so you can get potentially better accuracy than one sound path the only time we we traditionally or would would recommend one sound path is when you install it with to sound paths and now you’re looking for your signal and your see you’re struggling to get a strong signal then you come and change it to one sound path and you would change the configuration so we’re going to start it off two sound paths hit enter now it gives us a recommended spacing distance and it’s saying three point one nine inches reflect mount that’s the distance that we’re going to set these transducers apart from one another and so we’ll start off we’ll mount one up on the pipe and then we’ll measure the other one out now three point one nine inches is not an easy distance to measure off the tape measure what we recommend you do and it’s quite acceptable is to average that off to plus or minus a quarter inch so if the three point one nine I’m going to average you up to three point two five now we won’t cheat the meter the last question the meter will ask us after we’ve completed the install is what did we actually space the transducers at so let’s get we have some flexibility easily a quarter-inch but on larger diameter pipes we can get a little bit more flexibility on the spacing there and sometimes we can even use that flexibility to fine tune the signal to peak it out and then ultimately the meter will ask us what spacing do we have it set at and we tell it main thing is that we tell the meter what we spaced to that we don’t deviate too much from what it recommended and then we tell it what we have it at we can’t have it out of spacing at six inches and tell it it’s at three inches because now we’ve lied to the meter and an error is going to result from that okay so we’ve got a couple of different means of mounting up the transducers I’m going to start off with the the most basic this is a this is our basic mounting kit the we have other types of mounting apparatuses that are additional now this is a a chain type you’ll get this this bracket here that slides into the top move of the transducer so we slide that in take out our coupling grease put a little bit of grease right down the center of the transducer don’t have to overdo it now this there’s an arrow if we’ve hold these through transducers up we’ll see that we can make an arrow with that now that kind of makes it foolproof what we want to do is face the outer in the direction of flow now on this pipe the flow is going this way so we’re going to face it that way okay so we’ll get the first one up there second one now at this point we can move

to our signal screen and we’re going to get some one of the nice features of this meter is that it gives us immediate feedback on the signal strength you’ll see that I can just hold this transducer to the pipe and approximately three inches and you’ll start to see the signal on the display want to zoom in on that there you go and you’ll see that I if I move the transducer around a little bit you’ll see I can I can see some varying amounts of signal and probably where I’m seeing the highest signal is going to want me where I wind up at the three inch point and once I get it once I get the chain on I’ll measure it out with the tape measure okay I’m going to show you this one more time I’m just holding one transducer on the pipe and you’ll see as I slide it I’m sliding in closer you see the signals dropping down now I’m sliding out you see the signal is increasing and this is closer to the 3-inch point now we don’t want to do that when we install a me to necessarily slide the transducer back forth I’m just giving you a demonstration here what we want to do is measure it out and put it at the recommended spacing we would only engage in that type of optimization if we had a weak signal so now begin I’m using my eyes right now to kind of psych what three inches are I kind of now I’ll measure it out put the tape and I did a pretty good job there that’s 3 and 1/8 and I said I was going to go for three and a quarter but since I got such a nice of three and eight rounded off there I’m going to leave it at 3 and 1/8 and I have to tell the meter I have it at 3 and 1/8 now I like the signal um the amount of signal that we’re looking for you zooming in on that now ok the amount of signal that we’re looking for is about three balls of signal as we get to as we get to about two and a half paws of signal we’ll see that that light is maybe starting to flicker red and so we need to get above two and a half three balls of signal to get a green light and that means we’ve got a good signal got to see a green light if you don’t see a green light we don’t have a good signal okay so we got green light lots of balls of signal you’ll find yourself of sort of rootin for the signal now because you know that when you put this thing on the pipe if you’ve got the three plus balls of signal and you have a green light you’re going to do good and the difference between having say three or four balls of signal and having six or seven balls of signal does not mean that I’m going to have a more accurate reading because I have seven balls of signal you just have to be above the minimum level okay so I like what I see I’m going to hit the enter key now move on to the next cell the last thing now that the meter is asking me is what distance did I space the transducers at I put it at 3 and 1/8 that’s 3.125 I enter in 3.125 now don’t forget to do that because the value that was in there was the value that was there from the last time you use the meter and if you’ll leave that alone it’s going to do a calculation based on the raw in an incorrect distance that he thinks that transducer is at so don’t forget this step now you tell the meter what distance you have the transducer space that you press enter and you’re ready to start measuring flow and will turn the flow on in this loop in a second here but just as a review I’m going to go through this again for you I’m going to show you kind of how easy getting this meter running is okay so we’re going to start this off once one more time here for you let’s hit the brake key now we hit the brake key any time we want to go back to the main menu screen anytime we want to go backwards if we’re going forward through the menu and we go one one beyond where we want to be there’s no real back arrow when we’re programming this meter up so we’ve got to hit the brake key and then get back to the main menu screen okay so now I’m going to hit the brake key now if you’ll just focus the camera on on the meter here I’m going to start at parameters going to hit the enter key parameters for channel a enter I’m going

to enter them enter in my pipe size it already has that values if I want to I can just hit the enter key but just for demonstration six point six two five we’re going to enter in the wall thickness 0.26 so the material hit enter no liar enter fluff this leave it alone enter the liquids water hit enter temperature 70 degrees hit enter I’m done with the parameter entries go over to measure hit enter I got a little check mark next to the a channel that’s the one we’re working with this is a channel the the plugin for the B channels over here on the meter hit enter that’s a tag number for the data logger we don’t have to put anything there if we don’t want to number of sound paths I’m going to change that to two now you’ll see that it’s D it defaulted itself back to one that’s because I went over to the parameters menu and it it created this it caused this to go back into a default State okay so I’m going to hit the to sound paths enter and it gives me the spacing distance three point one nine inches enter my signal strength lots of bars of signal enter my actual distance I put the meter at three point one two five enter and I’m reading flow now before I show you the flawless I just want to show you one more thing now uh this diagnostic screen the diagnostic that we call sound speed or sound velocity the sound speed of the liquid now one things we put in with the portable meter along with the pipe tables is you’ll see a chart here for sound speak and can you get a look at that you see that now you’ll see let’s say you know I have a temperature 70 degrees I don’t know if you can see that but it’s saying that the sound speed of the liquid should be fourteen eighty five point seven four seventy degrees now this is the sound speed of pure water this is not pure water that we have in this lab it’s got some minerals in it so we’re going to expect this that there you know we’re going to allow for some variation but this is what we call a check point now we know what the sound speed of water should be we know what it should be at 70 degrees and we’re going to we’re going to look that we’re going to look to see that that’s the sound speed we get if we don’t then it means that we did something wrong I’m show you how to get to the sound speed you want to zero in on the meter here again okay now when you’re in the flow screen over here the number three key up here along the three key it says display and along the nine key here it says display now the three key will show you information on the bottom display and the nine key will show you information on the top display so I’m going to three key the first thing it tells me is a flow velocity so I can see what my velocity is in in velocity terms in this case here feet per second but if I wanted to see it in meters per second I could change that unit and now sound velocity of the liquid and you’ll see that we’re getting a sound velocity of 1491 the table said that I should have four seventy degrees 1485 so that’s pretty close and I didn’t actually measure this water temperature but that tells me that I’ve installed a meter properly and that’s the biggest her–let that that you have to get over when you install the meter you there’s two main Diagnostics that you’re going to look to that tell you that I’ve done it right and if you do it right and you’re getting that proper diagnostic feedback you can trust the readings you’re going to have pretty accurate readings the meters are all wet flow calibrated to one percent and you know giving your piping conditions if you have a fast rate amount of pipe you’re going to be in that one one percent range so Sound speed is important as a good diagnostic check and signal strength as well but but Sound speed really told you that you’ve done everything right if for example I would have programmed the pipe dimension wrong I would have seen an error in the Sound speed now we’re talking about the sound speed of water here if you have a different liquid we have quite quite abundance of information on sound speeds we can provide you with some additional information you could call us and we could also discuss it and so that we could always give you an idea more or less based on that the type of application you have the liquid that you’re flowing more or less what your sound speed should be also as you’re learning as your using the meter you’ll learn about the sound speed of your liquid so you put it on one pipe you see what the sound speed

is then as you use the meter around the plant you’ll see that Sound speed is consistent for that type of liquid okay so if I hit the three key again I get back to the flow screen so it just toggled that bottom line it went from gallons per minute to flow velocity to Sound speed okay now we’ll hear this button here the eight key is queue on that’s all total so if I press that it turns on the totalizer on the top line so now um we’re going to turn on the flow a little bit here for you will see show you that the media actually measures flow okay I’m going to start up the flow now this is a reflection calibration lab that we’re working in and I’m going to dial in a flow of 300 gallons per minute now the response that you see is settable the media has a default not sure what this meter is set at right now looked like it we had about a 10 second response set in you’ll see that the flow is thought to settle into into the setting that I set the kallab for which three on a GPM okay the master meter right now in the cow lab is showing two 99.5 302 99.7 pretty good huh makes me look good okay now well now you see how easy it is to install a meter I’ll just walk you through another section of the menu give you an idea what’s what’s some of the features a choices are that you have here let’s hit the brake key will go over options I see the arrows go to options we’ll hit enter options for channel a enter now we can choose volume flow flow velocity mass flow thermal energy sound velocity okay back to wiring flow enter we can choose the units that we want to measure in gallons per minute gallons per day cubic feet per hour and then so on metric units leaders barrels and back two gallons per minute we can choose to have temperature measurement now this is a temperature sensor here and we have just pulled out of a case and this is a surface mount type temperature sensor that we have that goes with our portable meter or I’ll mount this up real quick over she goes pull on this it’s spring-loaded on the pipe plug this into the bulkhead where the temperature measurement goes now if I choose yes I’ll have a temperature measurement 42 now I’m actually I believe I’m plugged into t1 so I have to move this over to the to t2 slot dampening setting that’s the response time of the meter 10 seconds means it takes 10 seconds to rip up to the flow rate the trade-off there is response time versus stability so if I if I choose a larger number the response time will be slow but the meter will be more stable still measure data yes this is where we turn on our data logger serial output yes or no yes means that it’s going out in real time the serial port is up here on the bulkhead and yes means that it’s going out the only time you you would choose yes as if you have a laptop and you’re collecting data directly to the laptop otherwise you choose no and the data is going into the meter storage storage rate here we can choose what rate interval rate we want to store data at every 10 minutes every minute every 10 seconds we can choose extra in which case we can define the number of seconds we want to store data at let’s say I choose 10 seconds now if I choose a data rate storage rate of about 10 minutes the media will store from 4 to 6 weeks worth of data it

depends on how many channels we’re operating if we’re operating two channels it essentially will cut the time down in half current loop yes or no on the bulkhead we have two current options guys and we can we can output current will flow let’s say for example if we turn it on it would ask us what we want to set the maximum to in the minimum – so well well that’s pretty much it as far as the options in the meter we hit the break key our special functions over here contain things like how do you know setting up the clock time the storage the leading data that’s been stored parameter storage we can save up to 14 different sites pipe sites and and we manage that in the special functions but for the most part the parts of the menu that you need to use with the meter are really quite simple you go into parameters you tell it your information your pipe information liquid and then you go to measure it tells you what space to triage distance to put the transducers you install them when you got you’re eating so well I hope that that this tape here of get you going I hope that you get the most out of your f 601 portable meter I know that you will it’s the most robust portable meter that’s on the market today very high quality on the cable 14 hours battery on the portable meter you will really like this meter when you start using it me I happen to be very attached to mine and I don’t let it out of my sight when my colleagues come and try to borrow it I tell them to go fly a kite anyway thank you very much I appreciate you taking the time and if you if you have any more questions and you’re out there and you’re using this thing give us a call you do look us up numbers on on the field manual and course and we’ll help you thanks
