How Should I Select A Wastewater Electromagnetic Flow Meter?

Electromagnetic Flow meters are one of the commonly used instruments in wastewater treatment. According to the working principle, there are many types of electromagnetic flow meters, you need to choose the right electromagnetic flow meter according to the actual working situation.

• Reason 1

Electromagnetic flow meters have high accuracy(0.2% or 0.5%) and higher accuracy can be customized.

• Reason 2

Electromagnetic flow meters can be used on different pipe diameters from small DN(6mm) to quite large DN(3000mm).

• Reason 3

Temperature and pressure selection: Sewage electromagnetic flowmeter can measure the fluid pressure and temperature is a certain limit, selection, the use of pressure must be lower than the flowmeter specified working pressure. Sewage electro magnetic flowmeter operating temperature depends on the lining material used, generally -20 ℃ ~ 80 ℃, such as special treatment, can exceed the above range, the transmitter allows the measured medium temperature of -40 ~ +160 ℃.

• Reason 4

Electromagnetic flow meter generally consists of 5 parts (flange, liner, electrodes, sensor and transmitter). A wide range of liner and electrode options accommodate various process applications.

• Reason 5

Affordable price. Compared with other flow meters, magnetic flow meter is cost effective so it’s preferably considered by wastewater plants in terms of all the above-mentioned aspects.

• Selection of protection level

The sensors are available in IP67 and IP68 protection classes. If the actual installation location is in a low shaft, the sensors need to be IP68 dustproof submersible type.

• Selection of additional functions

      (1) For the selected basic type, electromagnetic flowmeter with LCD display, 4 ~ 20mA current output and 0 ~ 1KHz frequency output, according to the flowmeter and computer         communication requirements, the need to increase the RS-485 communication port function.

      (2) For the sensor is installed below the ground, should choose the split type.
