The LIT25 Level Indicating Transmitter is ideally designed to provide an excellent quality functionality for specific purposes. The transmitter has the ability to display, control and transmit several application levels. The user is advised to mount the non-contacting ultrasonic sensor on top of the tank and enclose it at the nearest convenient area. The user can also operate the device with the two-button keypad without the need to climb the tank. It is incorporated with a built-in relay specifically used for level control and alarm.
