Some precautions when operating an LNG dispenser

Some precautions when operating an LNG dispenser:
1. Pre-cooling operation: Before formal filling, pre-cooling operation is performed to prevent LNG from rapidly vaporizing.
2. Flow control: During the filling process, control the LNG flow to avoid a sudden increase in pressure caused by too fast filling.
3. Continuous monitoring: During the filling process, parameters such as liquid flow, pressure and temperature are continuously monitored to ensure a safe and smooth filling process.
