Product Critical Technical Advantages
-
Precision Engineered for High-Pressure Filling: The CNGmass is built to handle the intense demands of fast-fill gas stations, supporting process pressures up to 350 bar (5080 psi). Its measurement principle remains completely unaffected by the changing density or temperature of the gas as it is compressed into the vehicle tank.
-
Optimized for Custody Transfer: This flowmeter is purpose-built for legal-for-trade billing. The transmitter provides high-precision mass data directly to the dispenser’s controller, ensuring that every transaction meets the strict weights-and-measures requirements necessary for commercial fuel sales.
-
Enhanced Safety and Durability: To ensure maximum operational safety in high-pressure gas environments, the CNGmass is available with an integrated rupture disc. Its robust and ultra-compact transmitter housing is designed to withstand extreme ambient conditions while occupying minimal space inside the dispenser cabinet.
-
Multivariable Measurement Capability: By capturing mass flow, density, and temperature simultaneously in a single device, the CNGmass eliminates the need for separate sensors. This reduces the number of potential leak points—a critical safety factor when handling flammable, high-pressure natural gas.
-
Seamless System Integration: Featuring Modbus RS485 and pulse outputs, the CNGmass interfaces effortlessly with station POS (Point of Sale) systems and dispenser electronics. Because it requires no straight inlet or outlet piping runs, it can be installed in even the most compact dispenser designs.
-
Fast Commissioning and Data Security: Every CNGmass is delivered pre-configured to the application’s specific needs, allowing for rapid on-site startup. The automatic data recovery feature ensures that all configuration and calibration data are securely stored and can be restored instantly during maintenance.
