The ULX-… are configurable ultrasonic level probes for measurements from 0..5m to 0..60m that display the distance and depth on an LCD display, according to the parameters defined by the user.

These ultrasonic probes use sound waves to measure distances to visible surfaces without contact and wear.

They are used to measure the distance to any solid or liquid, opaque or transparent object. Environmental conditions such as smoke, dust, or rain have little effect on the performance of the ultrasonic sensor.
