What is the conductivity requirement of electromagnetic flowmeter?

Case introduction

1. The influence of conductivity on electromagnetic flowmeter

Electromagnetic flowmeter is a measuring instrument used for liquid and gas flow measurement. Electromagnetic flowmeters only have the measurement function for conductive liquids or gases. In the case of poor conductivity, signal propagation is susceptible to interference, resulting in inaccurate measurement results. Therefore, the conductivity requirements of electromagnetic flowmeters are also very important.

2. Conductivity requirements of electromagnetic flowmeters

Normally, the conductivity requirements of electromagnetic flowmeters should be above 0.1S/m. Only when the conductivity reaches above 0.1S/m can the electromagnetic flowmeter effectively detect and measure current and magnetic field. If the conductivity is lower than 0.1S/m, the signal output by the electromagnetic flowmeter will become weaker, resulting in an increase in error and serious drift, which will directly affect the use of the electromagnetic flowmeter.

3. Conductivity requirements in different application scenarios

Different liquids and gases have different conductivity capabilities. Therefore, in different application scenarios, the conductivity requirements for electromagnetic flowmeters are Also different. For example, for liquids such as sewage, slurry, acid and alkali solutions, and seawater, the conductivity should be higher than 0.1S/m; for gases such as gas, oil, and natural gas, the conductivity should be higher than 10^-6S/m. In practical applications, suitable electromagnetic flowmeter products should be selected according to different scene requirements, and the conductivity should be adjusted according to needs.

To sum up, the conductivity requirement of electromagnetic flowmeter should be at least 0.1S/m. At the same time, there are different requirements for the conductivity of electromagnetic flowmeter in different application scenarios. Understanding the conductivity of the electromagnetic flowmeter is of great significance for the correct use of the electromagnetic flowmeter.
