Magnetic flow meters (MAG flow meters) are volumetric flow meters that operate without any moving parts and are ideal for potable water and wastewater applications as well as ideal for any conductive or water based clean or dirty fluid.  Magnetic flow meters will generally not work with hydrocarbons, distilled water, and many non-aqueous solutions as they require a conductive fluid of 5 microSiemens/cm minimum.

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:

Quick video above showing how to use the front panel buttons. The SECRET password to CHANGE variables is 03210 where 00521 is for VIEWING only. To get back to NORMAL operation hold the Enter button (the rightmost button) for 3 to 5 seconds. Password to Configure Calibration 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. 

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.

 See video below:

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.

How to Reset the Totalizer in the MAG Meter. The Password to set the password for the totalizer reset is 19818.  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.

Vortex Meter Velocity Ranges:

The Vortex meter has different minimum and maximum flow velocities it can measure based on the fluid type and meter size. Please note the values below for proper sizing of your meter. 

• Steam:

• Gas: 

• Liquid: 

Nominal Vortex Flow Rates for Air

The table below gives the minimum, nominal, and maximum velocities for the Vortex Meter for gases to assist users familiar with Thermal Mass Flow Meter sizing guides relative to air, with a density of 0.075 lb/ft^3 for reference. As the pressure goes up the flows go up as well. For example, if the pressure is DOUBLED, so too does the mass flow. Download chart below here:

 IMPORTANT Note to Thermal Mass Flow Meter users...

Did you know that Multivariable Vortex Flow Meters offer a significant advantage over Thermal Mass Flow Meters when it is not necessary to measure ultra low or ultra high flows?

Did you know that a Multivariable Vortex Meter is not affected by gas composition? This means you can change gas composition and STILL report the proper Mass Flow! Why utilize a Gas Chromatograph to determine gas composition to correct your Thermal Mass Flow Meter measurement? If you need ultra low flows it makes sense but if your minimum flows are within the measuring range of a Vortex meter then consider a Multivariable Vortex Mass Flow Meter.

As well, it is important to note that Thermal Mass Flow Meters are quite sensitive to moisture in the flow stream. The most common undesirable effect is momentary flow spikes that can upset your control system. Vortex Meters, on the other hand are NOT sensitive to moisture in the flow stream and offer a significant advantage over Thermal Mass Flow Meters if such spikes are determined to be undesirable.

Have you ever have problems with temperature swings causing your Thermal Mass Flow meter to over or under report the flow measurement? The Multivariable Vortex Mass Flow Meter does not exhibit these symptoms simply because the vortex shedding velocity is not a function of temperature or pressure. And, with the Multivariable Vortex Meters built in Pressure and Temperature sensors you can get true Mass Flow, Pressure, AND Temperature and even gather Volume flow on those rare occasions when deemed necessary. And, you have a true pressure measurement as well as the Mass Flow and temperature. All at a price very competitive with Thermal Mass Flow Meters.

HOWEVER, if you DO need very low or very high flows we suggest the use of Thermal Mass Flow Meters. As well, Thermal Mass Flow Meters are ideal as "Insertion Meters" as they are small and if, and ONLY if, there is no moisture, or gas composition changes then the Thermal Mass Flow Meter is a very good choice.  Otherwise, the Vortex is the best choice as it has NO sensitivity to the gas composition or droplets or hydrocarbon particulate.

Refer to the chart above for the minimum and maximum flows for the Vortex Mass Flow Meter. Refer to the minimum and maximum velocities for the fluid you wish to use to see if a vortex meter is a good choice. If your flow is within the velocity range of the Vortex meter AND you have moisture or any change in gas composition then a Vortex meter is a better choice over the Thermal Mass Flow Meter.

Important Note: Vortex Flow Meters want to be rigidly mounted or isolated from vibration to prevent the vibrating energy to be transmitted to the Vortex Piezo Sensors. This can be accomplished by rigid mounts to a solid base or good vibration isolation.
