First, the influence of conductivity on electromagnetic flowmeter
Electromagnetic flowmeter is a measuring instrument used in liquid and gas flow measurement. Electromagnetic flowmeters have measurement functions only for conductive liquids or gases. In the case of poor electrical conductivity, signal propagation is prone to interference, resulting in inaccurate measurement results. Therefore, the conductivity requirements of electromagnetic flowmeters are also very important.
Second, the conductivity requirements of electromagnetic flowmeters
Under normal circumstances, the conductivity requirements of the electromagnetic flowmeter should reach more than 0.1S/m. Only when the conductivity reaches more than 0.1S/m, the electromagnetic flowmeter can effectively detect and measure the current and magnetic field. If the conductivity is lower than 0.1S/m, the output signal of the electromagnetic flowmeter will become weaker, resulting in an increase in error, and a serious drift phenomenon will occur, which will directly affect the use of the electromagnetic flowmeter.
3. Conductivity requirements in different application scenarios
Different liquids and gases have different electrical conductivity, so in different application scenarios, the conductivity requirements for electromagnetic flowmeters are also different. For example, for sewage, pulp, acid lye, sea water and other liquids should require a conductivity higher than 0.1S/m; For gas, oil, natural gas and other gases should require a conductivity higher than 10^-6S/m. In practical applications, the suitable electromagnetic flowmeter products should be selected according to the requirements of different scenarios, and the conductivity should be adjusted according to demand.
In summary, the conductivity requirements of the electromagnetic flowmeter should reach at least 0.1S/m, and in different application scenarios, there are different requirements for the conductivity of the electromagnetic flowmeter. Understanding the conductivity of electromagnetic flowmeter is of great significance for the correct use of electromagnetic flowmeter.
