Horizontal cistern: litres by liquid level

In a horizontal cistern the volume does not grow linearly with the level, so the dipstick needs a calculation. Enter the diameter, length and measured level — the calculator shows the litres in the cistern.

Approximate calculation using a simplified model: for designing equipment and process modes, consult a technologist.

Frequently asked questions

Why is half the level not half the volume?
Only at exactly half the diameter is the tank 50 % full. Above and below that level the dependence is non-linear.

The calculations are approximate: they help to assess the process and compare options, but do not replace a process design and trials on a specific raw material. This section is for reference only and contains no commercial offers.
