Product Critical Technical Advantages
-
Optimized for High-Pressure Refueling: Built to withstand the rigors of CNG stations, the CNGmass DCI operates reliably at process pressures up to 350 bar (5080 psi). Its dual-tube sensor design ensures that accuracy remains high even as tank pressure fluctuates rapidly during the filling process.
-
Custody Transfer Integrity: The transmitter is specifically designed for legal-for-trade applications. It delivers high-precision mass flow data that can be used directly for billing, supported by a pulse output and Modbus RS485 for flawless integration into station POS (Point of Sale) systems.
-
Enhanced Operational Safety: To protect personnel and equipment in the event of a primary tube failure, the CNGmass DCI is available with a rupture disc. The robust, ultra-compact housing is designed to perform under extreme environmental conditions, ensuring a long service life in outdoor fueling plazas.
-
Innovative Touch Control Interface: The device can be operated from the outside via “Touch Control,” allowing technicians to navigate menus and check diagnostics through the glass window. This is a critical safety feature that allows for maintenance and adjustment without needing to open the flameproof enclosure in hazardous areas.
-
Multivariable Efficiency and Small Footprint: Like all Coriolis meters, the CNGmass DCI captures mass flow, density, and temperature simultaneously. Because it requires no straight inlet or outlet piping runs, it can be integrated into the tight, space-constrained cabinets of modern CNG dispensers.
-
Reliable Data Recovery and Commissioning: Each device comes pre-configured for fast commissioning, significantly reducing setup time on-site. Furthermore, the automatic data recovery feature ensures that all configuration and calibration data are preserved during servicing, minimizing potential downtime.
