## User Guide

This tool calculates the volume of liquid held in a rectangular shaped tank using the measured level of the fluid. Where possible use internal dimensions to remove errors due to the thickness of the tank walls. It is assumed that the tank is installed on level ground.

### Tank Level & Dimensions

This calculator requires the following measurements to determine the amount of liquid in the tank.

#### Height of Liquid

Enter how high the liquid is from the bottom of the tank. If the outlet is not positioned close to the bottom of the tank then deduct the height difference in order to determine the usuable amount of fluid held in the tank.

#### Height of Tank

This the fixed measurement of the tank height. If the overflow and outlet are not positioned close to the top and bottom of the tank then subtract the height difference of each from the total tank height so that the usable capacity of the tank is factored into the percentage of fill calculation.

#### Length of Tank

Enter the length of the tank in your preferred measurement units. Ideally this should be the inside length, if the thickness of the tank wall is significant.

#### Width of Tank

Enter the width of the tank in your preferred measurement units. Ideally this should be the inside width, if the thickness of the tank wall is significant.

### Contents of Tanks

The quantity of liquid held in the tank is calculated here. If you have entered the outside dimensions of the tank and not considered the thickness of the tank walls in your measurements, the answer will be higher than the correct amount.

#### Volume of Liquid in Tank

The calculated volume of liquid derived form the fluid height entered above will show here.

#### % Full Tank

This indicates the fill amount compared to the maximum capacity of the tank and is displayed as a percentage value.
