CNGmass Coriolis Flowmeter
Brand: Endress+HauserCNGmass Coriolis Flowmeter
Brand: Endress+HauserWhen 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.
- Measuring principle operates independently of physical fluid properties such as viscosity or density
