The IMP Lite is a cost-efficient alternative to IMP+ for level measurement. It can be used whenever non-contacting ultrasonic level measurement is needed. The DATEM echo processing technology makes the Lite ideal for liquids, solids, and any application requiring the level to be displayed.

In the full range of IMP units, the wetted parts are in a PVDF build. Battery life is increased with the high-speed boot function of up to approximately three seconds. This means that if the Lite were to be switched on every 15 minutes for a three-second reading, the average current would only be 40µA. Dimensions include overall diameter of 5.12" and overall height of 6.9". For system integration, particularly in older installations, passive and active analog outputs are helpful.
