Abstract
A level sensor and housing therefor, the level sensor provides a measurement of the depth in a sewer manhole or chamber. The level 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. The narrow ultrasonic beam with limited spread will allow measuring level in a sewer manhole or confined chamber or any sewer where the level is measured close to a vertical wall.
