General Description
The ULS-100/10 Series Liquid Level Detection System is an ideal, low cost, ultrasonic liquid
level detection system for many applications. It operates in a broad spectrum of viscous to
light liquids.
Principle of Operation
The ULS-100/10 Series operates using ultrasonic sound wave propagation. Ultrasonic sound
waves are greatly attenuated when transmitted through air. Conversely, when liquid is
present, transmission of the sound waves is greatly enhanced. The electronic control unit
generates electrical signals that are converted to bursts of ultrasonic energy at the sensor. The
ultrasonic bursts are transmitted across the liquid sensing gap. Upon receipt of a valid signal,
the solid-state electronics generate a data enable condition, indicating liquid is present. This
signal energizes a relay to provide a contact closure or a 4 mA/20 mA, 2-wire current output.
