LIT25 Level Indication Sensor Description：

User's Manual Datasheet

The LIT25 is a level indication sensor that displays, controls, and transmits level. The non-contacting level sensor mounts at the top of a tank and the compact, watertight display enclosure is mounted at a convenient location nearby. Operators can calibrate the LIT25 with its 2-button keypad, without climbing to the top of the tank, enabling organizations to gain better stock and inventory control and tank level measurement that complies with health and safety regulations.

Use the built-in relay for level control or alarm, the large 4-digit display for local indication, and the isolated 4-20mA output to transmit level to a PLC. The standard ultrasonic level sensor measures liquid levels up to 9.8 m (32 ft) and includes automatic temperature compensation allowing for that all-important, reliable, level measurement even when conditions within the application are changing. The optional all-Teflon sensor enables the LIT25 to provide level measurement for chemical applications and all ultrasonic sensors are available with optional intrinsic safety approvals for installation in hazardous rated locations.
