ABSTRACT:
A leak detection system having a tank with a tank bottom and a containment baffle disposed above the tank bottom defining a containment space therebetween. The containment baffle supports a stored material within the tank. An inert gas supply is connected to the containment space for passing an inert gas into the containment space. An inert gas flow sensor is interactive with the inert gas supply so as to sense the flow of inert gas into the containment space. An alarm is connected to the inert gas flow sensor so as to produce a humanly perceivable signal in relation to gas flow above a predetermined limit. A leak detector is also provided interactive with the containment space for detecting and sending signals in relation to the presence of materials within the containment space. A pressure regulator is interactive with the inert gas supply so as to limit the pressure of inert gas within the containment space. The pressure regulator and the flow sensor are provided along a conduit from the inert gas supply to the containment space.
