What are the suitable media for measuring with electromagnetic flowmeters and vortex flowmeters?
Thread Content
Vortex flowmeters can measure both gases and liquids, so can electromagnetic flowmeters measure gases and steam? (Electromagnetic flowmeters are good at measuring liquids.)
An electromagnetic flowmeter is a device used to measure volumetric flow rate, and the measurement of flow rate is not affected by changes in the fluid’s density, temperature, pressure, viscosity, or conductivity. Electromagnetic flowmeters cannot be used to measure gases, steam, or liquids containing a large amount of gas. The conductivity of the liquid medium under test must not be lower than 5 μs/cm (equivalent to the conductivity of distilled water); in addition, organic solvents cannot be measured. Vortex flowmeters are suitable for measuring liquids, gases, steam, and some mixed-phase fluids, but they are limited in applications with high viscosity, low flow rates, and small pipe diameters. Vortex flow meters using force-sensitive detection methods should not be used in areas with strong vibrations.
