Product Critical Technical Advantages
-
Targeted Design for Dispenser Integration: The D8CB is “designed to meet application needs,” meaning every aspect—from its compact size to its communication protocols—is optimized for the tight internal cabinets of CNG dispensers. It provides the “brain” for modern refueling stations, ensuring reliability day and night.
-
Resilience Under High Pressure: Built to withstand the rigors of fast-fill stations, the D8CB handles process pressures up to 350 bar (5080 psi). Its measurement accuracy remains stable even as the gas density changes rapidly during the vehicle tank equalization process.
-
Space-Saving Transmitter Footprint: The D8CB features a robust, compact transmitter housing that delivers full functionality on the smallest possible footprint. This allows machine builders to reduce the overall size of their dispensing units or add more components into the same space.
-
Enhanced Safety Protocols: Operational safety is paramount when handling compressed flammable gases. The D8CB is available with an optional rupture disc to provide a controlled release in the unlikely event of a primary measuring tube failure, protecting both the equipment and the station surroundings.
-
Modbus RS485 for Seamless Data Exchange: The integrated Modbus interface allows for optimal data exchange with station controllers and Point of Sale (POS) systems. This ensures that mass, density, and temperature data are transmitted digitally without the risk of signal interference.
-
Efficient Multivariable Measurement: By capturing mass flow, density, and temperature in one device, the D8CB reduces the number of individual sensors required. Furthermore, since it requires no straight inlet or outlet piping runs, it offers maximum installation flexibility in dense piping manifolds.
