Why can't electromagnetic flowmeter measure high temperature medium

I believe everyone knows that electromagnetic flowmeters have certain requirements for the medium to be measured. Why do some people want to use electromagnetic flowmeters to measure high-temperature media, but use other such as vortex flowmeters to measure high-temperature media. Can it be? For the problem of high temperature medium, let me talk to you about it. Electromagnetic flowmeter is an instrument that uses the principle of electromagnetic induction to measure the flow of conductive fluid according to the electromotive force induced by the conductive fluid passing through an external magnetic field. It can be used in industrial and management departments such as environmental protection, metallurgy, medicine, papermaking, chemical industry, water supply and drainage, etc. The electromagnetic flowmeter can measure the flow of general conductive liquids, as well as the liquid-solid two-phase flow, high-viscosity liquid flow and the volume flow of salts, strong acids, and strong alkali liquids. It can be used in many different places, but there are still many deficiencies in its use, which will be introduced here. The main shortcomings of electromagnetic flowmeters are as follows: (1) Electromagnetic flowmeters are easily affected by external electromagnetic interference. (2) It cannot be used to measure steam, gas and liquid containing a large amount of gas. (3) It cannot be used to measure liquid media with low conductivity, such as organic solvents or petroleum products. At present, electromagnetic flowmeters are powerless. (4) Ordinary industrial electromagnetic flowmeters cannot be used to measure high-temperature media due to the limitations of measuring tube lining materials and electrical insulating materials; if they are not treated, in order to avoid dew condensation (frost) outside the measuring tube from damaging the insulation, they cannot be used. For the measurement of low temperature medium. Now whether it is good for electromagnetic flowmeters or high temperature media, do you all have a new understanding? If you don't know how to select a flowmeter for measuring high temperature media again, please feel free to call for details. Inquiries, or log in to Kaidi's official website for detailed inquiries.
