Compare Diesel Level Sensors

Gill offers a range of diesel level sensors designed for specific tasks: LevelPro, LevelLite, and LevelDefend  


Gill diesel level sensors are designed for use with a wide range of fuels used in different application types including diesel level sensors for genset applications. 

Our range of diesel level sensors uses highly dependable capacitive sensing technology, they provide reliable service in harsh environments where temperatures change and vibration is present.

Models are available to suit a range of tank depths and installation can be angled or inverted to suit compact or unusual installation types. Due to their design our diesel level sensors provide a damped response to reduce the effect of fuel sloshing when in mobile vehicles.
