Greyline LIT25 Tank Level Transmitter

Greyline LIT25 Tank Level Transmitter

The LIT25’s ultrasonic, echo-ranging sensor mounts at the top of the tank to continuously monitor level. A built-in temperature sensor is included to automatically compensate for changes in speed of sound due to temperature.

The standard sensor is rated for tank sizes up to 9.7 m (32 ft) high, and is made with PVC and Teflon (an optional all-Teflon model is also available). The sensor and cable are rated intrinsically safe (with an optional intrinsic safety barrier) for installation in hazardous rated tanks.

Easy Calibration

Calibration is quick and easy, using the 2-button keypad built into the unit to directly enter the measurement span and relay set points in centimeters or inches. There are no calibration targets or level simulations required, the values are stored in the unit through power interruptions, requiring no battery.

Level or Temperature Control

Calibrate the versatile LIT25 relay for your choice of level alarm, pump control, temperature alarm, or echo loss alarm. Relay On and Off set points are independently adjustable through the LIT25 calibration keypad. You can even control the LIT25’s response to an echo loss condition – hold the last reading, output 20mA, or output 4mA.
