A microprocessor controlled apparatus monitors a plurality of flow meters for computing and displaying the flow rates detected by each flow meter, the total volumes accumulated through each flow meter, the sum of the current flow rates for the flow meters, and the sum of the total volumes for the flow meters. The information from which the computations are made and the system operating parameters are transferred to a non-volatile memory in response to electronic means for detecting when a power outage or interruption occurs.
