System Configuration
Dual Fueling Nozzles – Enable simultaneous or independent LNG dispensing for two fueling positions.
Coriolis Mass Flow Meter – Measures LNG mass flow with high accuracy regardless of fluid density changes.
Cryogenic Piping System – Transfers LNG while minimizing heat ingress and maintaining cryogenic conditions.
Differential Pressure & Temperature Sensors – Monitor operating conditions for accurate measurement and system protection.
Emergency Shut-off Valve (ESD) – Immediately isolates LNG flow during abnormal operating conditions.
Breakaway Couplings – Automatically seal both ends if excessive pulling force separates the fueling hose.
Check Valve & Safety Relief Valve – Prevent reverse flow and protect the system from overpressure.
Industrial PLC & Controller – Controls fueling sequence, data processing, alarms, and safety interlocks.
Human-Machine Interface (HMI) – Displays fueling data, operating status, and diagnostic information.
Explosion-Proof Electrical System – Ensures safe operation in hazardous LNG fueling environments.
Technical Advantages
Dual-gun configuration allows two fueling operations simultaneously, improving station throughput and reducing vehicle waiting time.
High-precision Coriolis mass flow meter delivers ±1.0% measuring accuracy for reliable custody transfer.
Dynamic filtering and low-flow compensation maintain stable measurement accuracy across the 3–80 kg/min flow range.
Automatic zero calibration and temperature compensation minimize measurement drift during continuous operation.
Industrial-grade PLC control system provides reliable operation, fast response, and convenient future software upgrades.
Patented breakaway protection system automatically seals both hose ends after accidental separation, improving operational safety.
