LNG dispenser is special equipment with metering and pricing devices, which fuels LNG to storage vessels. It consists of flowmeter, regulating valve, gas gun, gas return gun, gas return hose, electronic controller and auxiliaries etc.
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℃. Valve and pipelines are insulated by full vacuum structure. Simple pipeline arrangement reduces the gasification rate of LNG.
