Sewer Flow Measurement: A State-Of-The-Art Assessment

Abstract

A brief review of the characteristics of storm and combined sewer flows is given, followed by a general discussion of the need for such flow measurement, the types of flow data required, and the time element in flow data. A discussion of desirable flow measuring equipment characteristics presents both equipment requirements as well as desirable features and includes an equipment evaluation sheet that can be used for a particular application.

A compendium of over 70 different generic types of primary flow measurement devices, arranged according to the fundamental physical principles involved, ispresented along with evaluations as to their suitability for measurement of storm or combined sewer flows. To illustrate the implementation of the physical principles, a number of commercially available devices for flow measurement are briefly described.
