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.
