Abstract:
1. A method of determining the flow rate of a single dispensing point for a dispensing transaction in a service station using dispensing point dispensing start and end event data and tank probe fuel level data from a fuel tank which supplies fuel to the single dispensing point, comprising the steps of: (a) receiving tank level data that is a record of the tank level of the fuel tank that supplies fuel to the dispensing point to formulate a plurality of tank level data points; (b) determining the start of the dispensing transaction using a dispensing start event for the dispensing point; (c) determining the end of the dispensing transaction using a dispensing end event for the dispensing point; (d) defining a region of interest in the plurality of tank level data points between the start of the dispensing transaction and the end of the dispensing transaction; (e) determining the amount of fuel dispensed by the dispensing point in the region of interest; (f) calculating the flow rate of the dispensing point for the dispensing transaction based on the amount of fuel dispensed by the dispensing point in the region of interest and the duration in the region of interest; and (g) storing the calculated dispensing flow rate.
