It is equipped with a series of safety devices, such as a safety valve. When the pressure in the tank exceeds the set value, the safety valve will automatically open and release some gas to prevent the tank from exploding due to excessive pressure. The emergency shut-off valve can quickly cut off the LPG delivery pipeline in emergency situations, such as collision, fire, etc., to avoid large-scale leakage of LPG. There are also monitoring devices such as liquid level gauges and thermometers, which can monitor the liquid level and temperature of LPG in the tank in real time, allowing the driver to understand the transportation situation at any time.
