    Abstract: A method of testing a product for leaks includes providing a pressure system (14, 240, 340, 440) for applying to the product a reference pressure that is less than 50.6 KPa. The method also includes developing a gas flow through a leak detection sensor (9, 220, 320, 420) in response to applying the reference pressure to the product. Another step of the method includes determining, based upon the gas flow between the prodct and the pressure system, whether the product leaked an unacceptable amount during the test period.

    Abstract: A method and apparatus (10) is disclosed for detecting leaks in a container (16) utilizing ultrasonic detection of airborne molecular movement of gas. An inlet (12) allows passage of gas into the container (16) at a predetermined pressure. An inlet passageway (18) receives the gas and transfers the gas to the container (16) via an outlet passageway (20). An ultrasonic transducer (24) is coupled between the inlet passageway (18) and the outlet passageway (20) for detecting movement of the gas as the gas enters the apparatus (10) and determines when the container (16) is completely filled upon detecting an absence of movement of the gas. The ultrasonic transducer (24) is further operative to detect subsequent movement of gas when the gas is allowed to enter the container (16) after the container (16) has been completely filled, wherein the subsequent movement of gas is indicative of a leak in the container (16).

    Abstract: A system for determining a leak rate of a device during an adiabatic cooling phase (Fig. 6) is provided. The system includes a leak rate training system (116) receiving leak rate calibration data, such as pressure data or mass flow data for a device having a known leakage rate. The leak rate training system generates an adiabatic cooling model (600) from the leak rate calibration data, such as by solving a finite differente equation for one or more unknown process variables that are dependent on the adiabatic cooling parameters of the device. The system further includes a leak rate detection system (700) receiving the adiabatic cooling model and leak rate data and determining a leak rate component of the leak rate data using the adiabatic cooling model, such as by using the variable values determined through solving the finite difference model to interpolate between the leak rate calibration data that was gathered using known leakage rates.

    Abstract: A method and system for detecting leaks in a fuel dispenser (12) is operative to pneumatically pressurize a selectable one of a vapor recovery portion and a fuel dispensing portion using a compressed air flow (14). A flowmeter (18) measures the flow rate of the compressed air communicated to the fuel dispenser for pressurization thereof. A processor (32) provides an indication of the leakage condition of the fuel dispenser based upon the pneumatic flow rate measured by the flowmeter (18) which satisfies a pressurization condition for the fuel dispenser, such as maintaining the pressurization level above a threshold value. The flow rate of compressed air needed to maintain this pressurization level is indicative of the leak rate.
