The selection principle and advantages of electromagnetic flow meter
Electromagnetic flowmeter selection principle:
1, the measured liquid must be a conductive liquid or slurry;
2, caliber and range, is the normal range of more than half of the full range, the flow rate between 2-4 meters;
3, the use of pressure must be less than the flow meter pressure;
4, different temperatures and corrosive media use different lining materials and electrode materials.
The measurement accuracy of electromagnetic flowmeter is established in the case of liquid filled pipeline, and the measurement problem of air in the pipeline has not been well solved at present.
The advantages of electromagnetic flowmeter: no throttling parts, so the pressure loss is small, reduce energy consumption, only related to the average speed of the measured flow body, wide measurement range, a wide range of use.
