The liquid level display is inaccurate; what can be done about it?
Thread Content
The medium used in the refrigeration system of our equipment is ammonia. In the evaporator, liquid ammonia and gaseous ammonia coexist, and when the temperature is below -20°C, it becomes impossible to detect the liquid level, which poses significant difficulties for daily operation. Is there any good way to solve this problem?
Differential pressure level gauges for cryogenic equipment – those that can operate at -196°C work as well; let’s see if it’s feasible~
Reply to 2# SuperFree2316: It’s not just the low temperature; the state of gas-liquid mixture also plays a role
In low-temperature states, it’s always a gas-liquid mixture~
