How to choose the suitable liner under high temperature ?

Electromagnetic flowmeters are mainly used to measure highly corrosive fluids, some of which may have temperatures inside the pipeline that are mostly around 100 degrees Celsius, and some may even reach 200 degrees Celsius.
In order to adapt to different temperatures, electromagnetic flowmeters need to use different materials for the lining. PTFE (polytetrafluoroethylene) lining can withstand temperatures below 100 degrees Celsius.
PFA lining can withstand temperatures below 180 degrees Celsius. PTFE and PFA have different levels of softening at different temperatures. However, when the softening temperature is reached, the sealing at the
electrode hole will become worse, causing leakage and damage to the electromagnetic flowmeter!
