The Groz Drum Oil Level Indicator checks the fluid remaining in a drum or tank, such as oil, fuel, water, and coolants. This cost-effective tool easily fits onto the small 3/4" hole on drums, leaving the 2" opening free for installing pumps. The polyethylene planetary gear mechanism float is held by a string that moves down as the liquid level goes down in the drum.

For use with: Oil, Water, Windshield Fluid, Antifreeze, Detergents, Diesel

NOTE

This is not a precise measuring device. The gauge is only to give an approximate/indicative level of liquid in the drum to know when to arrange for a new drum.
