Model ULSS/ULSM/ULSL Ultrasonic Level Sensor

Brand: Dwyer Instruments, LLC
Does not ship to United States
The Series ULSS Ultrasonic Level Sensors provides non-contact, continuous ultrasonic level measurement of fluids for short range applications.

It has a 4.1' (1.2 m) measuring range with a 0.125" (3 mm) accuracy.

The Series ULSM Ultrasonic Level Sensors provides non-contact, continuous ultrasonic level measurement of fluids for medium range applications.

It has a 9.8' (3 m) measuring range with a ±0.2% of range accuracy.

The Series ULSL Ultrasonic Level Sensors provides non-contact, continuous ultrasonic level measurement of fluids for tall range applications.

It has a 18' (5.5 m) measuring range with a ±0.2% of range accuracy.
Features
  • 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
