The main control circuit of the Overfill Protection & Earthing System is designed with a highly integrated special chip and a voltage monitoring circuit scheme; high integration, strong anti-interference ability, stable and reliable performance; the controller alarms and outputs dry contact signals, which can be easily connected to other controls system.

The system is widely used in the safety interlock control of fluid delivery processes in petroleum, chemical, food and other industries. It is suitable for electrostatic grounding detection and oil spill protection and alarm in the delivery process of top-mounted crane pipe or bottom-mounted crane pipe. It can effectively prevent accidents caused by static electricity, and at the same time avoid oil spills during the loading process, and ensure safe operations in dangerous places such as oil depots and chemical plants. The equipment complies with the relevant safety standards, and is suitable for vehicle loading occasions for flammable, explosive and other liquid petrochemical products.

Overfill Protection & Earthing System is a modern new technology equipment, which is widely used in the control of fluid distribution process in petroleum, chemical, food and other industries. It can effectively prevent accidents caused by static electricity and avoid oil spill accidents during loading. Safe operations in dangerous places such as oil depots and chemical plants are especially suitable for occasions where the turnover of liquid petrochemical products such as flammable and explosive products is frequent.
