ABSTRACT:
A liquid leak detector for use with above-ground storage tanks. The liquid leak detector includes a vertically upright standpipe for filling with a liquid to a level that generates a hydrostatic head pressure substantially equivalent to that exerted by the liquid in the storage tank; a first pipe connected to the standpipe at about the bottom end thereof and adapted to be connected to the tank at about the bottom of the tank; a pressure transducer disposed within the first pipe for sensing hydrostatic head pressure differential between the liquid in the storage tank and the liquid in the standpipe to determine a change in pressure differential resulting from a change in the amount of liquid in the storage tank; and a hose connected above the level of the liquid in the standpipe and adapted to be connected to the tank above the level of the liquid in the tank.
