FUEL DISPENSER WITH FRAUD DETECTING BREAKAWAY VALVE ASSEMBLY

A fuel dispenser includes a fuel nozzle configured to be connected to a vehicle fuel system, fuel piping configured to transfer fuel from at least one fuel storage tank associated with the fuel dispenser through the fuel nozzle into the vehicle fuel system, and a fraud detection valve apparatus. The fraud detection valve apparatus includes a cutoff valve configured to selectively prevent flow of fuel, a flow sensor configured to sense a flow of fuel, and processing circuity. The processing circuitry is configured to receive an indication of flow of fuel through the fuel flow control valve apparatus, determine an authorization status, and in response to a determination of no authorization during flow, cause the cutoff valve apparatus to close. 一种燃料分配器，包括燃料喷嘴，其配置为连接到车辆燃料系统；燃料管道，其配置为将燃料从与燃料分配器相关联的至少一个燃料储罐通过燃料喷嘴传输到车辆燃料系统中；以及欺诈检测阀设备。欺诈检测阀设备包括截止阀，其配置为选择性地阻止燃料的流动；流动传感器，其配置为感测燃料的流动；以及处理电路。处理电路配置为接收通过燃料流动控制阀设备的燃料的流动的指示，确定授权状态，且响应于确定流动期间无授权，使截止阀设备关闭。
