The CNGmass DCI is specially designed for refueling with environmentally friendly natural gas (CNG).

The Coriolis Flow Measuring Principle

Refueling application flowmeter with seamless system integration

CNGmass DCI is specially designed for refueling with environmentally friendly natural gas (CNG). The natural gas volume can be both measured with precision and displayed directly onsite. The device is operated from the outside via “Touch Control” and can be operated at any time during maintenance. A MODBUS interface is included for optimal data exchange.

  • Benefits

    • 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

    • High flexibility in system integration –...

  • Field of application

    • 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...
