Abstract
A velocity sensor and housing therefore, the velocity sensor provides a measurement of the velocity in a sewer manhole or chamber. The velocity sensor includes an ultrasonic transducer that emits a signal to measure the liquid below and may use an additional transducer or it is used by itself to detect the signal reflected from the surface. A parabolic reflector is designed and arranged to direct the emitted ultrasonic signal from the transducer to the surface with a linear beam while minimizing the beam spread. The return echo may either be measured directly or with the same transducer that was used to transmit the ultrasonic signal.
