It is very useful to be able to calculate the volume of liquid in the following tanks:

• Cistern
• Pump
• Reservoir
• Tank
• Upper part of the reservoir
• Lower part of the reservoir
• First stage of the showerhead
• Second stage of the showerhead
• Output pipe of the showerhead
• Pipe connecting the output pipe to the tank
• The volume of the liquid in the tank

It is very important to use the right units, because the result of the calculation will be different if the units are not the same. In addition, the screen displays an image of the tank and the liquid level in it at the appropriate scale.
