Independent Secondary Shutoff Control System® - Spill Prevention Technology
With the environment, life safety and product security in mind, we developed the proprietary patented GuardDog to continuously monitor from 1 to 2 sets of Overfill Detection and Static Ground units, from 1 to 8 individual product meter pulses, up to two vapor recovery hose pressure transducers, and from 1 to 8 individual preset pump commands per unit.
Under normal conditions the GuardDog is silent, until its predictive intelligence predicts valve failure within 750 msec of a wet probe event. Upon the predicted valve failure, it immediately leaps into action to shutdown pumps, close storage tank base valves and lock out the loading operation. It alerts management personnel of the problem and provides an opportunity for investigation. The GuardDog gives management control by not allowing loading to continue or resume until management determines that it is safe to load again by initiating a keyed system reset switch.
Not only does the GuardDog stop potential spills in their tracks, but it also sniffs out potential leaks, prevents over pressurization of cargo tank and attempted sabotage and product theft. It prevents catastrophic events while maximizing performance and minimizing false positives. The GuardDog gives management significant improvement in facility safety, security and control.
