  • Patent number: 9878896
    Abstract: A meter for measuring the flow rate of fuel in a fuel dispenser comprises a housing with an axial bore extending therethrough and defining an inlet and an outlet. A flow indicating mechanism comprising one or more rotatable components are mounted in the axial bore of the housing and configured to rotate as fuel flows from the inlet to the outlet, wherein each rotation indicates fuel flow. A pulse generating device senses rotation of the rotatable components and generates an output signal indicative of the fuel flow. Finally, a vapor generating device is configured to generate vapor bubbles that flow through the flow indicating mechanism.

  • Patent number: 9804016
    Abstract: A method and apparatus for improving the accuracy of fuel flow meters by compensating for the presence of vapor bubbles generated within the flow meter. The method comprises measuring the temperature of the fuel flowing through the meter and using an algorithm or static lookup table to determine a vapor compensation factor based on that temperature. Because the tendency of fuel to vaporize depends largely on seasonal variations in fuel temperature, applying a temperature-dependent vapor compensation factor promotes year-round accuracy of the flow meter output.

  • Publication number: 20160016783
    Abstract: Systems and methods for monitoring fluctuations in the operation of the electromechanical valves of a fuel dispenser over a series of fueling transactions and identifying trends that may indicate mechanical wear of the valve or other fuel system issues. By identifying these issues before fuel dispenser performance is negatively affected, an operator may be notified and preventative maintenance or corrective action may be initiated before the issues affect the customer or gas station throughput.

  • Patent number: 8285506
    Abstract: An apparatus for generating a measure of fluid. The apparatus comprises a flow meter and a pulser having an identifier and a memory. The pulser is associated with the flow meter for generating pulser data indicative of a volume of fluid delivered through the flow meter. The pulser may alter the pulser data using correction data stored in its memory to generate altered pulser data. The pulser may store at least one of the pulser data and the altered pulser data in the memory. The apparatus further comprises a switch operatively connected to the pulser's memory. The switch is operative to vary the memory of the pulser between a write-protected and a write-enabled mode. Also, the apparatus comprises a controller in communication with the pulser and a serial communication circuit which enables communication between the pulser and the controller. Communication between the controller and the pulser includes the identifier.
