Collecting liquid product volume data at a dispenser

A dispenser for delivering a liquid product, the dispenser comprising:

• a pump meter that directs the liquid product from a tank and to a nozzle;
• a pulser cooperating with said pump meter, said pulser generating a plurality of pulses indicative of a volume of the liquid product that said pump meter directs to said nozzle;
• a first totalizer that receives a plurality of signals from said pulser for determining an amount of liquid product dispensed from at least one tank;
• a second totalizer, in parallel with said first totalizer, that receives said plurality of signals from said pulser for determining an amount of liquid product dispensed from the same at least one tank;
• and
• a data acquisition unit in signal communication with said first totalizer and said second totalizer, wherein said data acquisition unit receives from said second totalizer data indicative of a volume of the liquid product dispensed through said nozzle.

A method for collecting flow data using a dedicated totalizer within a dispenser, the method comprising:

• receiving a plurality of pulses at a first totalizer within the dispenser for determining an amount of liquid product dispensed from at least one tank;
• upon receiving data representative of said plurality of pulses from said first pulser at a second dedicated totalizer within the dispenser for determining an amount of liquid product dispensed from the same at least one tank, generating reading data indicative of a volume of liquid product flowing from the dispenser;
• and
• sending said reading data corresponding to said dedicated totalizer to at least one of a retail system and a centralized inventory management system.
