The investigation concerns a new, nonintrusive, low cost, passive flow measurement method to meet the urgent needs for good management of storm and combined sewer systems. Operation of the system is based on sensing the near field sound emitted by the disturbed flow at a channel discontinuity. These local pressure pulses are called pseudosound and radiate as dipole sound sources orthogonal to the flow direction. The output signal of passive transducers, such as accelerometers, attached to the outer wall of the channel indicates flow rate after processing by a Fourier Analyzer. Feasibility has been demonstrated by laboratory tests using full scale sewer pipe elements, and by a brief series of field tests measuring sanitary sewage flow. Recommendations are made for further field site testing using an instrumented sewer line.
