ABSTRACT:
Liquid flow through a sewer or water pipe or conduit is measured by admitting the liquid into a confining region of known dimensions from an open end of the pipe or conduit at such rate as to maintain the liquid depth constant in the pipe or conduit and determining the volume of liquid entering the region within a given time period. The depth in the pipe or conduit is conveniently monitored as static pressure of liquid, as is the depth in the confining region. Air is educted from the confining region as necessary to ensure admission of the liquid thereinto at the desired rate for constant in-pipe depth.
