ULK-500 and ULK-1000 are configurable ultrasonic level probes for measurements from 0..5m to 0..10m that present 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.
