Overfill Prevention & Grounding System – Top Loading
Description
Overfill Prevention and Grounding Systems provide overfill protection as well as grounding verification and are designed for top and bottom loading of tank trucks, rail cars, etc.
Overfill prevention and ground verification controller has the function of static conducting and overfill prevention. Static ground monitoring system is used in the loading system of liquid chemical products. Tank truck static grounding protection can be interlocked with automatic control system. When the liquid level reaches the sensor or there is ineffective grounding, Explosion-proof electrostatic grounding alarm will send out acousto-optic alarm and output signal to stop the valve and pump to prevent overfill and ensure static grounding.
