The alcohol-based liquid fuel and the plastic are subjected to oxidation reaction, so that the aging period of the plastic is accelerated, the container becomes brittle and breaks quickly, fuel leakage is caused, and fire and explosion accidents are caused. 3. The container is not provided with corresponding safety accessories and monitoring devices, the state of the fuel in the container cannot be determined, people often need to open the container to observe the internal state, and poisoning and fire are easily caused. 4. When a large area fire occurs, the fuel inevitably explodes.

The second type is galvanized iron square barrel/cask, and its advantage is low price, and the transport is light, can derive static, and the shortcoming is: 1. the fuel and galvanized iron sheet are corroded, so that the wall perforation of the container is easy to leak, and a fire disaster is caused. 2. The container is not provided with corresponding safety accessories and monitoring devices, the state of the fuel in the container cannot be determined, people often need to open the container to observe the internal state, and poisoning and fire are easily caused. 3. When a large area fire occurs, the fuel inevitably explodes.

High level alarm

Before the feeding pump starts to work, the dry self-sealing quick connector 7 is connected to start feeding into the storage container 9. When the liquid level sensor 402 detects that the liquid level value of the storage container 9 reaches a high liquid level set value, the controller 8 controls the display 12 to flash in red, the controller 8 cuts off the power supply of the electronic lock box 5, and meanwhile, the controller 8 uploads data to the background management system.

Low level alarm

When the liquid level sensor 402 detects that the liquid level value of the storage container 9 reaches the low liquid level set value, the controller 8 controls the display 12 to flash in red, and the controller 8 sends a message to the background management system.

Second, high pressure alarm
