Tips: What is an electromagnetic flow meter? What are the characteristics?

A magnetic flowmeter or electromagnetic flowmeter is an instrument, based on the principle of electromagnetic induction, to measure the flow rate of a conductive fluid by the electromotive force induced by the conductive fluid going through an external magnetic field. The structure of the magnetic flowmeter is mainly composed of magnetic circuit system, measuring conduit, electrodes, housing, liner, and converter.

Magnetic Flowmeter Features:
1. The measurement is not affected by changes in fluid density, viscosity, temperature, pressure and conductivity.
2. There is no component to obstruct the flow in the measuring tube without pressure loss and with low requirement for the straight pipe section.
3. If choosing reasonable sensor lining and electrode material, the magnetic flowmeter will has good corrosion resistance and abrasion resistance.
4. The converter uses a novel excitation method, featuring low power consumption, zero point stability, high accuracy.
5. The converter can be integrated with the sensor, i.e. integral type or be separated from the sensor, i.e. remote type.
6. The sensor’s induced voltage signal is linearly related to the average flow velocity, so the measurement accuracy is high.

Existing reviews of Magnetic Flow Meter for Sewage Water/Wastewater, DN15-DN200

We would like to know if this flow meter can work properly under pressures higher than atmospheric pressure

What we found is that the flow meter displays a much lower flowrate number when it is connected behind a pump. So, we would like to know if this flow meter can work properly under pressures higher than atmospheric pressure.

ATO Responded

Yes, the flow meter is connected to the back of the pump, the pump will have pressure loss, and the overall pressure in the pipeline will drop, so the flow meter displays a much lower flowrate number.

When installing, please try to make the straight pipe between the pump and the flowmeter as long as possible, about half a meter would be better. This flow meter can work normally at pressures above atmospheric pressure.

Best magnetic flow meter I've ever used

This is the best magnetic flow meter I've ever used. Not only is it affordable, but most importantly, it performs well. I have been using this magnetic flow meter for five months without any problems.

This mag flow meter works perfect.

Bought this magnetic flow meter for measuring the wastewater, and it was mounted easily with flange. The split type is really convenient for me to operate this item and measure the wastewater. Works perfect.
