Electromagnetic flowmeters are widely used in chemical and chemical fiber, food, paper, sugar, mining and metallurgy, water supply and drainage, environmental protection, water conservancy and hydraulic engineering, steel and other industrial fields to measure various acid-base, mud, pulp and other conductive liquid media Volume flow. Its all-Chinese electromagnetic core converter uses a high-speed central processing unit. The calculation speed is very fast, the accuracy is high, and the measurement performance is reliable. The sensor of the electromagnetic flowmeter adopts the new technology of non-uniform magnetic field and the special magnetic circuit structure, the magnetic field is stable and reliable, and the volume is greatly reduced, and the weight is reduced, so that the flowmeter has the characteristics of small and light weight. The measuring principle of the electromagnetic flowmeter is Faraday's law of electromagnetic induction. The main components of the sensor are: measuring tube, electrode, excitation coil, iron core and yoke shell. It is mainly used to measure the volume flow of conductive liquid and slurry in closed pipelines. Including acid, alkali, salt and other highly corrosive liquids.

Electromagnetic flowmeter instrument selection
 Confirmation of measuring range
For general industrial electromagnetic flowmeters, the measured medium flow rate should be 2～4m/s. In special cases, the minimum flow rate should be no less than 0.2m/s, and the highest should be no more than 8m/s. If the medium contains solid particles, the usual flow rate should be less than 3m/s to prevent excessive friction between the lining and the electrode; for viscous fluids, the flow rate can be selected to be greater than 2m/s, and a larger flow rate will help automatically eliminate the adhesion on the electrode. The role of stagnant objects is conducive to improving the measurement accuracy.
Under the condition that the range Q has been determined, the size of the flowmeter diameter D can be determined according to the range of the above-mentioned flow rate V, and its value is calculated by the following formula:
Q=πD2V/4
Q: Flow rate (㎡/h) D: Pipe inner diameter V: Flow velocity (m/h)
The range Q of the electromagnetic flowmeter should be greater than the expected maximum flow value, and the normal flow value should be slightly larger than 50 of the full scale scale of the flowmeter.
