MODEL ULSM ULTRASONIC LEVEL SENSOR

9.8'(3 m) Measuring Range, Non-Contact Transmitter, 4 SPST Programmable Relays

The Model ULSM Ultrasonic Level Sensor provides non-contact, continuous ultrasoniclevel measurement of fluids for medium range applications. Ultrasonic technology pairedwith automatic temperature compensation provides accurate and reliable measurements inalmost all conditions. The Model ULSM has failsafe logic that is easily configured to customapplications via free software removing the need for target calibration. Using the freesoftware, the Model ULSM can be programmed to transmit an output signal as well as setthe four relays for control applications. This rugged design comes with a NEMA 6Psubmersible enclosure rating to ensure a long lasting unit.
