The machine is designed for final levelling of sulphuric acid into automotive batteries. The individual batteries supplied through the conveyor of the finishing line are positioned exactly. The fill stroke moves down, and the individual levelling heads are lowered into the filling holes of the battery. The level controlling by sensors in each head, facilitates a quick and exactly level achievement. Whenever the level is reached the fill stroke raised up and the battery is feed out of the machine and the next batteries are feed into the exact levelling position under the fill stroke.
