ABSTRACT:
A pump station flowmeter is disclosed including a sudden high inflow change detection circuit for eliminating from a series of emptying characteristic calculations taken over a period of time those measurements which are outside of a predetermined acceptance range. The wet well dimensions, level detector signals, clock signals and pump status signals are supplied as inputs to both a volume rate of change calculator and to the sudden high inflow change detector. In the event of an undesirable measurement, the sudden high inflow changes detection circuit operates a gate to isolate the volume rate of change calculator from the emptying characteristic calculator that calculates outflow. A flow integrator is provided for calculating volume per cycle from the volume rate of change signal, and an inflow calculator serves to produce inflow from the volume per cycle signal.
