Split electromagnetic flowmeter in the purchase of parameters

The split electromagnetic flowmeter is an inductive instrument that measures the volume flow of conductive media in pipes based on Faraday's law of electromagnetic induction. It is widely used to measure the volume flow of conductive liquids and liquid-solid two-phase fluids. The measurement results are related to the fluid's Temperature, viscosity, density, pressure and liquid-to-solid composition ratio have nothing to do with it, and the conductivity will not affect the measurement results even if the conductivity changes within a wide range. Therefore, after calibration with ordinary water, it can be used to measure the flow rate of other conductive liquids or liquid-solid two-phase fluid media without any additional corrections. Therefore, the split flowmeter is a true volumetric flowmeter.

The selection of split electromagnetic flowmeter is the same as that of other flowmeters. The measurement parameters on site under working conditions are the important core of instrument selection. The main parameters include diameter, measuring medium, working temperature, working pressure, flow range, lining and electrode materials, accuracy requirements and other parameters. In particular, the chemical properties of the measured medium are related to the success or failure of the selection. First, if the medium is a strongly acidic medium, the lining of the electromagnetic flowmeter should be a corrosion-resistant polytetrafluoroethylene lining. For electrode materials, alloy materials such as platinum and titanium should be selected. To extend the application life of the electromagnetic flowmeter. Secondly, if the medium is highly alkaline and contains impurities with relatively high oil hardness, you can choose a ceramic lining and stainless steel as the electrode material. Therefore, the chemical properties of the medium must be clear.
