摘要： A dual piston/poppet valve in a fuel dispenser works with a two-stage valve to help eliminate errors from an inferential flow meter. When the two-stage valve opens partially, a secondary fuel path is opened in the dual piston/poppet valve. A sensor detects the opening of the secondary fuel path and reports its opening to a control system. The two-stage valve opens fully and a primary fuel path is opened concurrently, During transaction completion, the two-stage valve partially closes, resulting in the closing of the primary fuel path. When the two-stage valve closes completely, the secondary fuel path closes. The sensor detects the closing of the secondary fuel path and reports the closing to the control system. Based on the outputs of the sensor, the control system accepts or declines input from a flow meter.
摘要翻译：加油机中的双活塞/提升阀与两级阀配合工作，有助于消除推理流量计中的误差。当两级阀部分打开时，双活塞/提升阀中的辅助燃料路径打开。传感器检测次级燃料通道的开启并将其开启报告给控制系统。两级阀门完全打开，同时打开主燃料路径，在交易完成期间，两级阀门部分关闭，导致主燃料路径关闭。当两级阀门完全关闭时，辅助燃油路径关闭。传感器检测到辅助燃油路径的关闭并将关闭报告给控制系统。根据传感器的输出，控制系统接受或拒绝来自流量计的输入。
