The“Overfill Protection and Earthing Systems” are designed for bottom loading of tank trucks, rail cars, etc. In the event of an overfill condition, the overfill sensor will send a signal through the output relay to the terminal automated loading system to shut down the loading operation. The systems provide overfill protection as well as grounding verification.
It especially suitable to be used Zone 2 where the highly inflammable and explosive petrochemicals are frequently transferred, such as:
1. The loading of gasoline, diesel, kerosene and other light oil.
2. The loading of liquid benzenes and hydrocarbons.
3. The canning system of other chemical products.

1. Capable of monitoring tank trucks with up to 6 compartments when equipped with optical sensors
2. The video demo shows the whole loading process
3. The 8 inch LCD screen provides a complete process animation demonstration for the staff to operate according to the process and understand the working condition of the system in time.
4. P02 plug meets API Recommended Practice. Connected with sockets on trucks, it monitors the grounding and overfilling status during loading process in time.
5. The external intrinsic safety touch screen can be set humanized without opening the cover to enhance human-computer interaction
6. With the cooperation of self-testing socket, display the truck compartment status of alarm, fault, shielding and other information in all time to ensure the safe loading.
7. Outputs on-off signal that indict the status of liquid level and static grounding to the Terminal Automation System.
8. Compatible and interchangeable with optical overfill sensors and sockets that meet API standards.
9. Real-time ground loop detection and resistance value display.
10. Outputs the homing signal and detects homing status of the plug.
11. Ensure the resistance value between the tank truck to the grounding point is not higher than 60Ω (meets the stipulate of lower than 100 Ω required by Chinese government).
12. We offer standard installing bracket.
