Endress+Hauser CNGmass Coriolis flowmeter

Refueling application flowmeter with easy system integration

• Measuring principle

  Coriolis

• Product headline

  This flowmeter can be easily integrated into refueling systems and provides accurate measurement of CNG usage. It is suitable for high pressure CNG refueling applications, offering precise measurement data.

• Sensor features

  Excellent operational safety is provided by this flowmeter, as it remains reliable even under extreme process conditions. By offering multivariable measurement of flow, density, and temperature, the number of required process measuring points is reduced. The compact, space-saving installation requires no inlet or outlet run. This flowmeter can handle flow rates up to 150 kg/min (330 lb/min) and process pressures up to 350 bar (5080 psi), making it well-suited for high pressure compressed natural gas (CNG) refueling applications.

• Transmitter features

  Easy operation is achieved by reducing the device to only the necessary application requirements. Fast commissioning is enabled through pre-configured devices. Automatic recovery of data facilitates servicing and maintenance. The transmitter housing is robust and ultra-compact in design. This flowmeter provides a pulse output as well as Modbus RS485 communication, allowing for easy integration into a variety of refueling systems.
