The Groz Drum Level Indicator is suitable for checking balance fluid remaining in a drum or tank. This cost-effective tool easily fits onto the small 3/4" hole on drums, leaving the 2" opening free for installing pumps. The planetary gear mechanism float is connected with a string and moves down as the liquid level goes down in the drum. 

The float can be used with various liquids, including oil, fuel, water, coolants, and more, with its polyethylene construction. Available in both litre and gallon versions, our Drum Level Indicators are commonly used in the oil and fuel industry.
