The Model ULSL Ultrasonic Level Sensor provides non-contact, continuous ultrasonic level measurement of fluids for applications up to 18 ft. (5.5 m). Ultrasonic technology paired with automatic temperature compensation provides accurate and reliable measurements in almost all conditions. This highly accurate unit has a blind zone of no more than 8 in (20 cm) and a beam width of no more than 3 in (76 mm), making it an ideal choice for small tank and container applications. 

The Model ULSL has failsafe logic that is easily configured to custom applications via free software, removing the need for target calibration. Using the free software, the Model ULSL can be programmed to transmit an output signal. Additionally, the software allows for the adjustment of the four relays perfect for control applications. This rugged design comes with a NEMA 6P (IP68) submersible enclosure rating to ensure a long lasting unit.
