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
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 – wide range of communication interfaces
GPsol, together with Endress+Hauser, developed a system that individually measures each component of extraction wells and provides as much information as possible about the current flow.
On the new factory calibration rig from Endress+Hauser, Wintershall Dea can now calibrate Promass F with hydrocarbons as legally mandated – a significantly cheaper option than on-site calibration.
The refueling application flowmeter with seamless system integration. Accurate measurement of compressed natural gas (CNG) in high pressure refueling applications.
