Selection of flowmeters for high temperature, high viscosity, and highly corrosive conditions
Thread Content
Dear experts: I am seeking information on a flow meter suitable for use with liquid metals at temperatures of 350–500°C, under normal pressure conditions. The viscosity of the liquid metal is very high, and the required measurement accuracy is 0.5%. What types of flow meters can be used? Feel free to discuss. **Drops have rewards.
Does liquid metal also corrode? Please specify.
Yes, there are some, such as liquid lead and liquid sodium. However, corrosion need not be considered for now, as there are already specialized materials for corrosion research.
Consider high-temperature ultrasonic flowmeters; Cologne seems to have one, but further consultation is needed. Someone on the forum said, “Ultrasonic measurements have been taken on molten salts at 550 degrees and high-temperature liquid sodium.” Link: http://bbs.hcbbs.com/thread-981030-1-1.html
