CNGmass DCI Coriolis Flowmeter

Brand: Endress+Hauser

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.

  • 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
Features
  • 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 – wide range of communication interfaces
  • Fast commissioning – pre-configured devices
  • Automatic recovery of data for servicing
