How is the pressure of highly viscous liquids at high temperatures measured on-site? Thank you
The temperature is very high; the silicone oil used for filling cannot meet the requirements, right?
I think it’s fine, because with flange-mounted pressure transmitters, the capillary tube causes some temperature loss; moreover, high-temperature resistant silicone oil can be used··
High-temperature silicone oil can only reach around 300 degrees, right? The temperature is too high; it’s easy to reach boiling point. There must be pressure fluctuations
The isolation tank should be filled with an isolation fluid, right? If the boiling point of that fluid is too low and the temperature of the medium is too high, it’s likely to boil
Only by selecting a compliant isolation fluid can more accurate measurements be achieved; the volume of the isolation tank should be large enough to ensure that no loss of the isolation fluid occurs.
