CNGmass - The flowmeter for accurate measurement of compressed natural gas (CNG) in high pressure refueling applications.

The Coriolis Flow Measuring Principle

  • Picture of Coriolis flowmeter CNGmass / 8FF for measurement of compressed natural gas (CNG)

Refueling application flowmeter with easy system integration

When it comes to billing and paying for the amount of CNG actually pumped, the measuring accuracy at the dispenser is just as important as with any other fuel. Therefore, the “brain” in every CNG dispenser is a flowmeter that measures the quantity of fuel transferred from dispenser to vehicle with the absolute highest accuracy – reliability day in, day out, round the clock. These are some of the benefits of CNGmass, which has been specifically designed for such applications.
