The Coriolis Flow Measuring Principle

Refueling application flowmeter with easy system integration

The market for natural gas is still growing! Compressed natural gas has long been established as an alternative fuel for vehicles. Compressed natural gas is also considered the cleanest fuel for combustion engines. The new CNGmass is specially designed for dispensers. With this Coriolis flowmeter the mass flow can be measured with highest accuracy — independent of pressure and temperature.
