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.
● Excellent operational safety – reliable under extreme process conditions
● Fewer process measuring points – multivariable measurement (flow, density, temperature)
● Space-saving installation – no in/outlet run needs
● Easy operation – reduced to application needs
● Fast commissioning – pre-configured devices
● Automatic recovery of data for servicing
● Measuring principle operates independently of physical fluid properties such as viscosity or density
● Accurate measurement of compressed natural gas (CNG) in high pressure refueling applications.
Device properties
● Flow rates up to 150 kg/min (330 lb/min)
● Process pressure up to 350 bar (5080 psi)
● Rupture disc available
● Robust, ultra-compact transmitter housing
● Pulse output and Modbus RS485
● Transmitter for custody transfer
