Description

Dwyer MODEL ULSL ULTRASONIC LEVEL SENSOR

18′ (5.5 m) Measuring Range, Non-Contact Transmitter, 4 SPST Programmable Relays
The Model ULSL Ultrasonic Level Sensor 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.
Ultrasonic technology paired with automatic temperature compensation provides accurate and reliable measurements in almost all conditions. 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 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.
