Magnetic flow meters (MAG flow meters) are innovative volumetric flow meters that provide accurate measurements of conductive liquids. Unlike traditional flow meters, they do not require any moving parts to operate. This feature makes them a reliable and low-maintenance option for measuring fluids in various applications. MAG flow meters are particularly suitable for measuring conductive liquids with a minimum conductivity of 5 microsiemens/cm2. They are commonly used in potable water and wastewater applications, as well as in processes that involve water-based clean or dirty fluids. However, it's worth noting that MAG flow meters are not suitable for hydrocarbons, distilled water, and many non-aqueous solutions, as these fluids do not meet the minimum conductivity requirement. Overall, MAG flow meters offer a unique combination of accuracy, reliability, and ease of use, making them a popular choice for a wide range of industrial and commercial applications. 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.

MAG Meter Installation requirements:

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.) If the meter indicates a NEGATIVE flow you may REVERSE the flow using Menu 8: Flow Direction and change it from the indicated value to either the REVERSE or FORWARD value. Note: If the flow indicates a NEGATIVE FLOW number AND you know it is going from LEFT to RIGHT Menu 8 may be used to FLIP the sign. The Flow Direct is a "switch" to take care of the "Right Hand Rule" with regards to the direction of the current vector in Faraday's Law and does not require the direction to agree with the arrow on the meter. If the meter indicates a  NEGATIVE flow on the display and does not output 4-20 mA it means that  Menu 13: SigmaN Ena can be set to ENABLE to allow the 4-20 to indicate flow in both the + and negative direction. Set Menu 13: SigmaN Ena to DISABLE if you do not want flow to indicate if the flow reverses. In this case the mA will go to 0 mA to indicate reverse flow, but not the magnitude in rate. However, the NEGATIVE Totalizer will account for the negative flow.   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. Note: The following display orientations can be ordered so the user does not have to orient in the field.

  Check out this brief tutorial video that demonstrates how to utilize the front panel buttons. What's interesting is that it requires a secret code to modify variables, which is 03210, while 00521 is solely for viewing purposes. In order to revert to the default mode, press and hold the Enter button (the rightmost button) for three to five seconds. Additionally, the password for configuring calibration settings is 19818.     Video above shows how to set up the Flow Units and Full Scale for those units. Note that this scaling is for driving the 4-20 mA and the frequency output so that the Full Scale value at 20 mA and at full scale Frequency is the number that is set. In this case the 4-20 and the frequency will output 20 mA and 5,000 Hz when the display shows 200 GPM. If the display goes OVER 200 GPM the 4-20 and the Frequency will increase until it "bumps it's head" on the maximum value. If the value on the display is GREATER than the value in Full Scale then one would adjust this value to accommodate the anticipated maximum value.     The video above shows how to set up the meter for Pulse and Frequency and shows how the 4-20 mA is configured.

See video below: IMPORTANT NOTE: This particular meter differs from most temperature and pressure transducers in that it is not "Loop Powered". It requires 500 mA to operate, making it impossible to function as a Loop Powered device. Therefore, it is crucial not to connect 24 VDC to the COM and I+ signal lines, where COM is linked to the "low" side (-) of the 4-20 mA and I+ is linked to the "high" side (+). Fortunately, your PLC has a mode that allows you to read the meter without providing power to it. The meter itself sources the 24 VDC, so supplying 24 VDC to the Current Output lines may void its warranty. Check out the tutorial video below for a comprehensive guide on how to authenticate and verify the 4-20 mA signal into your PLC or reading device. It's important to note that if you encounter any issues, such as a failure to authenticate the signal, a probable cause could be due to insufficient power supply. In order to power the meter effectively, it requires a maximum of 500 mA. To ensure proper delivery of power, it's recommended to have a power supply that has the capability to provide 500 mA, even during start-up where there may be an inrush current that can exceed 500 mA for a few milliseconds due to the electromagnetic coils.   How to Reset the Totalizer in the MAG Meter. The Password to set the password for the totalizer reset is 10000.  We show Clr Sum Key as the 24'th element in the menu structure. The video shows how to set the Totalizer Reset password to 10000.   How to use ModBusPoll on the TacticalFlowMeter MAG meter. Use this to ensure your configuration with your PLC is correct. How to set the Low Flow Cutoff if your flow meter is not showing flows at very low flows. You will use this if you notice the flow meter shows 0 flow when you know there is very low flow. The meter ALSO likely has the Response time set at 10 seconds so it suppresses very low flows further. Refer to THIS chart to find the lowest readable flow on YOUR size flow meter.
