Pump station flowmeter

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