ABSTRACT:
A sewer flow measurement method and system for determining flow conditions of a sewer line system wherein separately located monitors make and record precisely synchronized and time identifiable pressure measurements, utilizing pressure-to-signal transducers positioned on the bottom of pipes where they exit into manholes. A cassette recorder records the different pressure related signals from the monitors together with a discrete identification signal from each monitor. The outputs of the recorder are then fed to a pressure-to-flow computer which provides location identified, time synchronized, flow data for the system.
