OMEGA’s ultrasonic sensors deliver accurate and reliable liquid level detection with an SPST mechanical relay output. The technology provides a high level of ultrasonic sensitivity, including resistance to vapor and turbulence. The ultrasonic sensor utilizes a fork-shaped sensor which contains two piezoelectric crystals, one of which acts as the ultrasonic transmitter, and the other as a receiver. If the air gap between the points of the fork fills with liquid, the sonic wave passes from one crystal to the other.

Would last longer with a better wire.Works just as expected. We use it in a leg washer, and have bought the same sensor every year for 4 years. Only gripe is that the sensor inevitably fails because of weak wiring/connection point
