Flow Rates
Inline Ultrasonic flow meters (Ultrasonic flow meters) are volumetric flow meters for measuring acoustically conductive fluids [Not Gases] that operate without any moving parts and are ideal for potable water and wastewater applications as well as ideal for any non conductive or water based clean or dirty fluid. Ultrasonic flow meters will work with hydrocarbons, distilled water, DI water, and many non-aqueous solutions where the MAG meter is not capable or performing.
The table below gives a guideline of the nominal maximum GPM for various pipe sizes. Flows in well designed piping systems, to minimize wear and noise, and energy, are typically no more than 10 m/s max. Note these meters can easily go to 12 m/s for systems, such as high pressure fire fighting systems and blowdown systems.
Quick Notes
HELPFUL QUICK NOTES: Menu 90 shows Signal Strength and Menu 00 shows main flow rate and total. Also set menu 40, the Filter Coefficient, (We could call this the time constant or response time), with Menu 40 to 1 second to make the meter respond quickly. Then, put back to 4 seconds and save with Menu 26 and hit enter twice. Menu 45 is for entering a K-Factor, this would be handy if you KNOW the flow is 90 when it says 100. In this case a K-Factor of 0.9 would remedy it. (Ideally the distances and pipe thickness/material would be corrected but this is easier). Menu 70 and 71 allow LCD Display on time and contrast respectively
§3.1.6 Validating meter function.
Entering a pipe outer diameter (Menu 11) of zero, results in the display to show the flow velocity: 1.2345678m/s (4.0504ft/s) [use down arrow to view], flow rate= will vary, and display “R”status on Menu 00. Inputting a set value in M44 will change the totalizer output. Use this function to test of the flow meter and network software without having to connect the transducers. If they are connected the flow rate may be + or -

The video above shows how to set up the meter for Pulse and Frequency and shows how the 4-20 mA is configured.
Simulating and validating the 4-20 mA output using the User Interface with 03210 is detailed below. You may ALTER these values (AnalogZero and AnlgRange) using 03210 and they will revert when you exit.
Note the 4-20 mA output for this meter is POWERED by the meter. DO NOT connect to a PLC that provides 24 VDC. Connection is made to the 4-20 mA signal using a reading mode just like a Fluke Meter configured to read 4-20 mA DC. The MAG meter provides the 24 VDC for outputting the value to the INPUT of your PLC. Every PLC has the ability to be configured to read this type of 4-20 mA output. (Note: From the main menu the AnalogZero is 49 hits of the UP arrow.) (ADJUSTMENT of the 4-20 Output drive is attained using secret password of 19818 and is risky to use.)

IMPORTANT NOTE: This meter is not a "Loop Powered" device, unlike almost all temperature and pressure transducers that are loop powered. This meter takes 500 mA to run so you can see that they can not be Loop Powered. It is CRITICAL that 24 VDC is NOT connected to the 4-20 mA signal lines of COM and I+ where COM is connected to the "low" side,-, of the 4-20 mA and the I+ is connected to the "high" side,+. Your PLC has a mode in it to read these meters that does NOT involve sending power to the meter. These meters are SOURCING the 24 VDC. Connecting 24 VDC to the Current Output lines may void warranty.
The video below shows how to VALIDATE the 4-20 mA signal into your PLC or reading device. Note: If this DOES NOT WORK a likely cause is the power supply does not have enough "power" to provide to the meter. The meter requires a MAX of 500 mA so have a power supply that has the capability to DELIVER 500 mA, even on "start up" where the inrush current given to the electromagnetic coils can rush over 500mA for a few milliseconds.
