ABSTRACT:
A meter coupled in close proximity to an underground storage tank fuel pipe that delivers fuel from the underground storage tank to fuel dispensers in a service station environment. The meter measures the total amount of fuel drawn from the underground storage tank. The meter may be placed in a submersible turbine pump or in the main conduit that carries fuel to the fuel dispensers. The meter measurement is compared to the meter measurements in the individual fuel dispensers that receive the fuel drawn from the underground storage tank to determine if a discrepancy exists. A discrepancy may be indicative of meter tampering, meter calibration issues, and/or a leak in the fuel pipeline between the underground storage tank and the fuel dispensers. A leak detection test may be automatically performed if such discrepancy exists and/or an alarm condition generated and communicated.
