Which flow meter is suitable for liquid carbon dioxide at minus 40 degrees Celsius
Thread Content
Yesterday, a client wanted to purchase a vortex flow meter for measuring liquid carbon dioxide at -40 degrees Celsius. Theoretically, vortex flow meters can be used to measure fluids within a temperature range of -40 to 350 degrees Celsius, but is it possible to do so in practice?
I have ethylene at minus 105 degrees here; can I use an orifice plate?
Vortices at low temperatures are better, with higher precision as well.
A Coriolis mass flow meter can be used. -60°C.
OP, it’s not possible. Theoretically, it can withstand temperatures down to -40 degrees, but in practical applications a safety margin is necessary, usually keeping it around -20 degrees. I recommend using Coriolis flowmeters; some imported brands perform very well for low-temperature measurements.
Reply to 2# backhamm1982: It is recommended to use a low-temperature Coriolis mass flow meter, which can withstand ultra-low temperatures down to -200 degrees. The detailed selection information is too large; please contact me. QQ978008394, Mobile: 13916101910.
