With the environment, life safety and product security
in mind, we developed the GuardDogTM to
continuously monitor from 1 to 2 sets of Overfill
Detection and Static Ground units, from 1 to 8
individual product meter pulses, and from 1 to 8
individual preset pump commands per unit.
Under normal conditions the GuardDog is silent, but just
like a large Pit Bull, it leaps into action when a valve
failure is detected 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 and
attempted product theft.
Flexibility
The GuardDog is extremely flexible and easily integrated
into the load rack operation. Typical configuration
requires one
GuardDog per load lane. The unit works in concert with
our Pump & Valve Controller and other safety components
and emergency shutdown circuits to provide a fail-safe
mechanism for quenching flow when a valve failure is
detected. |
