Inline air flow meter3/20/2024 Note for Password Menu 47 System Lock unlock code is 8758 Menu 70 and 71 allow LCD Display on time and contrast respectively. (Ideally the distances and pipe thickness/material would be corrected but this is easier). In this case a K-Factor of 0.9 would remedy it. Menu 45 is for entering a K-Factor, this would be handy if you KNOW the flow is 90 when it says 100. Then, put back to 4 seconds and save with Menu 26 and hit enter twice. HELPFUL QUICK NOTES: Menu 90 shows Signal Strength and Menu 00 shows main flow rate and total. 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. The videos peertain top the Clamp on Ultrasonic as well as the inline ultrasonic as they use the smae "engine" (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.) Videos Every PLC has the ability to be configured to read this type of 4-20 mA output. The MAG meter provides the 24 VDC for outputting the value to the INPUT of your PLC. 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. DO NOT connect to a PLC that provides 24 VDC. Note the 4-20 mA output for this meter is POWERED by the meter. You may ALTER these values (AnalogZero and AnlgRange) using 03210 and they will revert when you exit. Simulating and validating the 4-20 mA output using the User Interface with 03210 is detailed below. The video above shows how to set up the meter for Pulse and Frequency and shows how the 4-20 mA is configured. MAG Meter dimensions/ Installation requirements If they are connected the flow rate may be + or - Dimensions Inline Ultrasonic Meter Dimensions Plumbing: Use this function to test of the flow meter and network software without having to connect the transducers. Inputting a set value in M44 will change the totalizer output. Menu 70 and 71 allow LCD Display on time and contrast respectivelyĮntering a pipe outer diameter (Menu 11) of zero, results in the display to show the flow velocity: 1.2345678m/s (4.0504ft/s), flow rate= will vary, and display “R”status on Menu 00. 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. Quick Notes HELPFUL QUICK NOTES: Menu 90 shows Signal Strength and Menu 00 shows main flow rate and total. Note these meters can easily go to 12 m/s for systems, such as high pressure fire fighting systems and blowdown systems. Flows in well designed piping systems, to minimize wear and noise, and energy, are typically no more than 10 m/s max. The table below gives a guideline of the nominal maximum GPM for various pipe sizes. 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. Inline Ultrasonic flow meters (Ultrasonic flow meters) are volumetric flow meters for measuring acoustically conductive fluids 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. Manual Quick Ultrasonic Instruction Manual Note: For 1 to 5 VDC output, add 250 Ohm resistor to 4 to 20 mA loop.Ultrasonic flow meter with simple data logger.Output: 4-20mA + 0-10K Hz + Standard ModBus RTU Communication protocol.Power Supply: Set up to use either 24VDC or a 86-240 VAC Universal Power Supply.Std Temp Spec for Transmitters 320 F (160 C).Response time: 150 ms measuring cycle typical.Flow rate: Supports velocities up to 40 f/s or 12 m/s.Pipe size: 1” to 6” special order up to 12".Medium: Any acoustically conductive fluid with less than 5% air bubbles or solids.Perfect for oils such as Diesel Oil and many other oils.įeatures LARGE LCD display, shows the Instantaneous Flow Rate, Total Flow, in user selectable units. Ideal for DI Water and many fluids that the MAG meter can not measure due to low electrical conductivity. Inline Ultrasonic Flow Meters at the prices of High-End Clamp On Ultrasonic Flow Meters and feature accuracies of 0.5% of READING.
