Tank Level Gauges for Cryogenic Tanks 

Diaphragm and Bellows type differential pressure instruments calibrated in weight or volume are effectively used in cryogenic tank level monitoring. Tanks can be stationery (vertical or horizontal) or they can be used in tanker transport vehicles. Most cryogenic instrumentation utilizes a “dry gauge” design where there is no internal liquid fill. This prevents any leaking or fouling of the tank system and no damage or accuracy issues due to liquid fill expansion when exposed to temperature shocks in cryogenic applications.
