Tankers can gather electro-static charge whilst driving, loading and unloading, especially in dry or salty environments. Correct electrostatic discharging of the tanker significantly reduces the risks of electrostatic sparks and consecutive explosions.
OPW Civacon manufacture a number of products designed to mitigate against static charge, as well offering overfill protection in the case of the 8800E.
The OPW CIVACON 8800E Overfill Prevention and Ground Verification Controller is designed for API bottom loading applications on single and multi-compartment tank trucks at fuel terminals, refineries and chemical plants.
The 8800E performs 2 basic functions;
There are a number of manufacturers whose rack monitor also perform these basic functions, the Civacon 8800E however, has a host of additional enhanced features which make it the most technologically advanced fail-safe rack monitor available to the industry today.

The GME4 provides automatic earthing of tank trucks and railcars to the ground to ensure safe loading and offloading operations at site. It is designed for discharging of electrostatic charge during both the loading and offloading of flammable liquids and is used across a broad range of chemical, pharmaceutical and fuel terminal applications. The method of discharging the GME4 uses is by grounding.
Tankers can get electro-statically charged during driving and/or (un)loading, especially under dry or silty environmental conditions. Proper electrostatic discharging of the tanker significantly reduces the risks of electrostatic sparks and consecutive explosions.
The GME4 performs 2 basic functions;
A non-conductive measuring principle is used to verify grounding and therefore it is resistant against incorrect usage. For instance, if the clamp is short circuited (e.g. connected directly to steel construction) this is evaluated by the GME4 as INCORRECT grounding and NO permissive signal will be generated.
