    CNG filling/unloading column uses high-performance industrial control microprocessing system, which is the metering equipment used in trade settlement of CNG main station or substation, and mainly filling/unloading & metering for CNG tank car.Temperature compensation is available as it uses imported mass flow meter with temperature sensor, high accuracy pressure sensor assures the high accuracy metering.Mass flow meter, manual ball valve, high pressure hose, quick coupling are imported from famous brand abroad.
    Designed and manufactured by ourselves, the computer controller uses industrial grade electronic components, and it passed the test of harsh environmental suitability, electromagnetic compatibility and safety, which assures the reliability of computer controller in complex operating environment. With proprietary intellectual property rights, there is no any obstacle in technology upgrading and rebuilding in future.Runner pipe path is φ22x4, high pressure hose diameter is 25mm, maximum flow reaches 80kg/min.



High accuracy of measuring, High reliability、Proprietary intellectual property rights、 Fast speed for filling
