Liquid level indicator: usable for commercial 60 l and 210 l barrels. Suitable for non corrosive liquids, such as cooling/lubrication concentrates, emulsions, oils, anti freeze, heating oil etc. and liquid media. Ideally usable for more transparency when handling the barrel. The float is located inside the barrel on the liquid and indicates the barrel content permanently on the volume scale. Since the Liquid level indicator is mounted on the 3/4“ opening you can put a pump on the 2“- bunghole at the same time, in order to allow pumping out the defined quantity.
