Gasoline dispenser leak detectors and automatic shut-off systems |
摘要 |
Methods and systems are disclosed for controlling dispensation of hydrocarbon fuels from storage tanks and the like, by employing a sensor in an environment proximal to the dispenser. The sensor preferably includes an optical waveguide having a central axis along which light can transmitted, and the waveguide is disposed in the environment, such that fuel present in the environment contacts at least a portion of the waveguide. The sensor further includes a light source for projecting light into a first end of the waveguide, and a detector for detecting the amount of light propagated through the waveguide. The sensor is electrically connected to a controller which terminates the dispensation of fuel in the event that a leak is detected by the sensor.
