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.
Abstract translation: 一种用于确定下水道系统的流动状况的下水道流量测量方法和系统，其中单独定位的监测器利用定位在管子底部的压力信号换能器来进行准确同步和记录时间可识别的压力测量，并将它们排出进入检修孔。 录像机记录来自监视器的不同的压力相关信号以及来自每个监视器的离散识别信号。 然后将记录器的输出馈送到压力到流量的计算机，该计算机为系统提供位置识别，时间同步，流量数据。

Abstract: A method and means of determining inflow (undesired pipe drains to a sewer) and infiltration (sewer pipe leakage) into sewer lines by a coordinate measurement of pressure in sewer pipes at several locations, particularly measuring flow during rainfall and for a discrete period thereafter and comparing the results with dry periods.
Abstract translation: 通过在几个地点的下水道管道中的压力的坐标测量，特别是测量降雨期间的流量以及之后的离散时间，确定流入（不利于管道排水到下水道）和渗水（下水管泄漏）的方法和手段，以及 将结果与干燥时期进行比较。
