Our Products

Level Sensors

Whatever your media, tank depth, and profile, SSI Technologies, LLC most likely has an ultrasonic liquid level sensor for you.

Our ultrasonic liquid level sensors use ultrasonic technology to generate a high-frequency sound wave to measure the time for the echo to reflect off of the target and return to the ultrasonic liquid level sensor. The distance from the ultrasonic liquid level sensor to the fluid is then calculated based on the speed of sound and the profile programmed into the sensor.
