ABSTRACT:
An apparatus for detecting leaks in a pipeline in a liquid dispensing system. The apparatus generally includes a tank containing a liquid, a dispenser valve disposed remote from the tank, a pipeline connected between the storage tank and the dispenser valve, a pump at the tank for supplying liquid under pressure to the pipeline and an isolation valve between the pump and the dispenser valve to isolate the pump pressure from the pressure in the pipeline between the isolation valve and the dispenser valve. The apparatus further has a pressure sensor between the isolation valve and the dispenser valve for measuring any pressure change in the pipeline between the isolation valve and the dispenser value. A leak simulation valve alternatively may be provided for draining the pipeline to simulate a leak.
