This is a discrete level sensor with self-diagnostics and tolerance to highly aerated fluids, with standard or custom outputs. Sensor probe materials include stainless steel, aluminum, ceramics, and some plastics. Sensor housing materials include stainless steel, aluminum, and many plastics.

Ultrasonic Discrete Flexural Wave Level Sensor

How The Discrete Flexural Wave Sensor Works

Ultrasonic flexural waves in a rod are readily dampened when immersed in a liquid. This becomes the basis of an inexpensive single level detector that can function in highly aerated liquids. The transducer creates flexural waves in a metal, ceramic or plastic cylinder.In the presence of a liquid these waves are drastically reduced in amplitude and this is detected as a change in voltage across the transducer. This is an inexpensive sensor that works in all liquids regardless of dielectric constant, viscosity, aeration etc.
