摘要： A vapor recovery system is disclosed that utilizes a crystal oscillator for sensing the presence of hydrocarbon in the vapor emissions emanating from a fuel tank during refueling. The crystal oscillator is coated with a layer of material having a sensitivity for hydrocarbon. In response to any interaction between the coating layer and hydrocarbon, the crystal oscillator experiences a shift in its oscillation frequency relative to the fundamental resonance frequency. The frequency shift is representative of the hydrocarbon concentration in the vapor emissions. A control signal based on the frequency shift is generated and then used to adjust the operating speed of the vapor pump.

摘要： A method and apparatus is disclosed for sensing hydrocarbon in the vapor path of fuel dispensers using a fiber-optic sensor. The sensor includes an absorber-expander sensing structure mechanically coupled to the fiber body and responsive to the presence of effluent fuel components for absorbing the hydrocarbon therein and expanding in response thereto. The expansion activity has the effect of generating a microbend deformation in the fiber, producing detectable changes in the optical throughput representing the concentration of hydrocarbon that is sensed by the absorber-expander element. The fiber-optic sensor is particularly useful in a vapor recovery system by providing an optical signal that is representative of the ambient hydrocarbon concentration. The concentration level of hydrocarbon represented by the detected change in fiber transmittance serves as the basis for regulating the rate at which the vapor pump collects effluent vapors discharged during refueling, namely by appropriately adjusting the vapor pump operating speed.

摘要： The method for detecting leaks in an above ground storage tank includes the step of first determining the level of water in the tank by establishing, in a container lowered into and resting on the bottom of the tank, a clean interface between water and a liquid hydrocarbon product in the tank which has entered into the container. Preferably the method includes an initial step of inserting a predetermined amount of water into the container before lowering the container into the tank. The method also includes sensing changes in conductivity along a line intersecting an interface between the liquid hydrocarbon product in the tank and water in the tank with a leak detector in a casing and establishing a clean interface in the leak detector to prevent debris at the interface in the tank from fouling the sensing of changes of conductivity. Further, the method of establishing a clean interface in the container or the casing includes lowering the container or casing which is substantially closed and which is provided with an opening at the upper end thereof into the tank until it reaches the bottom of the tank; opening an inlet/outlet opening in the lower end of the container or casing after it has settled on the bottom of the tank; and, allowing a clean interface to be established in the container or casing.
