CNG Dispenser

Compressed natural gas (CNG) dispenser is special equipment with metering and pricing devices, to fill compression natural gas to storage vessels. It consists of solenoid vale, check valve, mass flowmeter, electronic controller, rapid cut-off valve, and high pressure hose and so on. The control system of dispenser adopts the design of multi-core processing and intrinsic safety design. The core components such as mass flowmeter and solenoid valve can suit severely cold environment and can be used in low temperature of -40℃.

Function:

● Unit price and density setting.

● Quota and quantitative fueling.

● Sequential and non-sequential fueling.

● IC card fueling and Non-IC card fueling.

● Breaking protection, pressure limiting protection and emergency stop.

● Printing ,shift turnover.

● Cumulative fueling per shift ,total cumulative fueling functions.

● Fueling conditions inquiry, station management, and network management of fueling station.
