Equipment Configuration:Electromagnetic flowmeter

Electromagnetic flow meter is a common flow measurement instrument, mainly used to measure the flow of conductive liquids.

Project Overview

  Electromagnetic flow meter is a common flow measurement instrument, mainly used to measure the flow of conductive liquids. However, some media can not be measured by electromagnetic flowmeter. The following are some electromagnetic flowmeter can not measure the medium:

  1. gas: electromagnetic flowmeter can not measure the gas, because the gas is not a conductive liquid, can not cause the magnetic field reaction.

  2. non-conductive liquid: in addition to gas, some non-conductive liquids, such as oil, water, etc., can not be measured by electromagnetic flowmeter. Because these liquids can not cause the magnetic field reaction, can not be measured.

  3. conductive solids: some conductive solids, such as metal powder or metal particles, etc., also can not be measured by electromagnetic flow meter. Because these solids are highly conductive, will interfere with the magnetic field of the electromagnetic flowmeter, affecting the accuracy of the measurement results.

  4. High-temperature liquids: electromagnetic flowmeter is usually suitable for liquid measurement at room temperature, if you need to measure high-temperature liquids, you need a special high-temperature electromagnetic flowmeter. Because high temperature will make the liquid molecules heat movement intensified, affecting the accuracy of the measurement results.

  5. organic solvents: some organic solvents, such as benzene, toluene, etc., can not be measured by the electromagnetic flowmeter. Because these solvents are non-polar molecules, can not cause the magnetic field reaction, can not flow measurement.

  In short, the electromagnetic flowmeter has certain limitations, can not be all media flow measurement. In the selection of flow measurement instruments, need to be measured according to the nature of the media and measurement requirements for comprehensive consideration.
