    User Guide

    Use this calculator tool to determine the amount of contents in a upright cylinder shaped liquid storage tank from the measured height of fluid in the tank.

    Tank Level & Dimensions

    Specify the following reading and tank dimensions

    Height of Liquid in Tank

    Enter the height measured from the minimum level to the top of fluid in the tank

    Height of Tank

    Enter the height of the tank which should be the difference in height between when the tank is empty and when it is full.  If you only know the outside height of the tank from top to bottom, then the accuracy of the volume calculated will depend on the positional height of the overflow outlet at the top of the tank and the feed line at the bottom of the tank.

    Diameter of Tank

    Enter the inside diameter of the tank, which if you were standing inside the tank would be the widest distance from one side of the tank to the other.  If you only know the radius of the tank, then multiply this by 2 to determine the diameter.  If you only know the outside diameter of the tank, it is okay to use it, but the error of the calculated volume will be dependent on the thickness of the tank wall.

    Contents of Tank

    The amount of liquid in the tank is calculated here.

    Volume of Liquid in Tank

    The volume of the liquid contents held in the tank are displayed here in your preferred volumetric units.

    % Full Tank

    This shows the percentage of tank capacity that is filled.
