LNGmass flowmeter for accurate measurement of cryogenic gases in refueling applications

The Coriolis Flow Measuring Principle

  • Picture of Coriolis flowmeter LNGmass / D8LB for refueling applications

Refueling application flowmeter with easy system integration

LNGmass is a Coriolis flowmeter specifically developed for dispensers, guaranteeing highest accuracy and robustness at extreme subzero temperatures down to –196 °C (–321 °F). Due to the most compact design worldwide, the device can be installed anywhere, even in the narrowest space conditions without any problem. The LNGmass has no moving parts and is, therefore, absolutely maintenance-free.
