ABSTRACT:
A probe adapted to fit in an open end of a sewer or water conduit is provided with a weir plate and with a bubble tube for sensing the depth of flow over the weir plate and, thus, determining the flow rate. A V-notch weir plate is made up of two like pieces flexibly joined at their apex, thereby enabling the probe to be compressed for ease of insertion into the open end and to be expanded therewithin for frictional retention against the inside wall of the conduit, to which the probe conforms. Except for the weir plate itself all parts of the probe lie along the wall for minimum disturbance of the flow.
