Abstract
Flow velocity of a liquid stream in a sewer or water pipe or conduit is determined by injecting electrically conductive fluid transversely of the flow and measuring the time for the increased conductivity to be sensed at a given location downstream from the injection location. In conjunction with measurement of flow depth as by bubbling a gaseous fluid into the liquid stream and determining the back pressure applied thereto by the overlying liquid, highly accurate monitoring of flow rate and volume becomes feasible.
