  • Publication number: 20050126307
    Abstract: A flow switch used in conjunction with a fuel meter in a fuel dispenser to determine when fuel is flowing. A flow switch can only be activated if fuel is flowing through the flow path of the flow switch. If fuel is flowing as indicated by the fuel flow switch, but the meter is not registering fuel flow, there is a meter error, which may be an error internally with components of the meter and/or a pulser that generates pulse signals indicative of fuel flow. If the meter pulser is registering fuel flow, but the flow switch is not registering fuel flow, then an error exists with the flow switch. If fuel is flowing and there are no errors, both the meter and the flow switch should indicate fuel flow.

  • Publication number: 20050028610
    Abstract: A flow switch used on conjunction with a fuel flow meter in a fuel dispenser to determine when fuel flow rate signals form a fuel flow meter should be ignored in the calculation of flow rate and/or volume of fuel dispensed. An inferential fuel flow meter may be used as the fuel flow meter. The inferential fuel flow meter may be a turbine flow meter that comprises one or more turbine rotors that rotate in response to fuel flow flowing through the turbine flow meter. The turbine rotors may continue to generate pulses even when fuel is no longer flowing. A flow switch determines when fuel is actually flowing and fuel is not actually flowing. The flow switch is described as either a single poppet or dual poppet flow switch in examples described herein.
