Truck Grounding Controller for Vehicle Ground Verification

Designed for Flammable Liquid Transfer

Key Features & Benefits

SeeLeveL PosiGround - black-red

Model 672-H

The SeeLeveL PosiGround ™ Truck Grounding Control System helps prevent fires and explosions caused by a static discharge that builds up during the transfer of flammable liquids. Monitors the ground status and can be set for either 250-ohm high-resistance range or a 10-ohm low resistance range; activates alarms if the ground connection is lost during transfer.

Operation Overview

The SeeLeveL PosiGround™ system operates by connecting one clamp to a grounded metal object and the other to a second grounded metal object at least 20 feet away. Ideally, both objects should have a buried portion. The display will indicate when a valid ground is detected and loading or unloading has not yet started. Ground resistance can also be viewed on the display if required.

If loading begins before a ground connection is established, or if the ground connection is lost during operation, a warning horn will sound. If the connection is not made or restored within the preset time, the final alarm will activate. After loading is complete, shut down the loading system and disconnect the ground clamps.
