 The Model ULSS Ultrasonic Level Sensor provides non-contact, continuous ultrasonic level measurement of fluids for short range applications. Ultrasonic technology paired with automatic temperature compensation provides accurate and reliable measurements in almost all conditions. The Model ULSS 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 ULSS can be programmed to transmit an output signal as well as set the four relays for control applications. This rugged design comes with a NEMA 6P submersible enclosure rating to ensure a long lasting unit.

• Has a 4.1´ (1.2 m) measuring range with a 0.125" (3 mm) accuracy
• Via free software, units can be programmed to transmit an output signal and operate four relays for control applications
• Provides reliable, accurate, and non-contact level measurement of compatible liquids
• Non-contact technology offers no moving parts to wear, jam, corrode, or get coated like contact technologies
• Mapping software makes effective measuring surface only a 3" (76.2 mm) diameter column with no concerns of ladders, pipes, or other tank intrusions in the remaining sound cone
• Ultrasonic technology paired with automatic temperature compensation provides accurate and reliable measurements in almost all conditions
• Fail-safe logic is easily configured to custom applications via free software removing the need for target calibration
• Full NEMA 6P submersible enclosure rating to ensure excellent product durability
