Tankulus app for iPhone and iPad

Use this app to estimate various storage tank attributes such as length, volume, diameter, fill percentage, 90% ullage, stick readings, etc.

Do you need to set an overfill prevention valve and dont know the height at which to set it? 
Must convert inches of product (stick reading) to gallons? 
The tank monitoring console needs to be reprogrammed, but you dont have a tank chart available? 
Configuring an overfill alarm without wanting to do any calculations? 
About to make a delivery and wondering if your load is going to fit without overfilling the tank? 
Tankulus can do all of that and more, just input the details and use the slider to adjust the values, its that simple!

Supported tanks are flat-ended cylindrical horizontal, flat-ended cylindrical vertical, and rectangular. All measurements are in inches/gallons. Use for gasoline, diesel, DEF, water, and oils. Calculations are based on perfect geometric shapes and assume inside dimensions of tanks. Actual tanks may not be perfectly shaped, and may have hidden features that this calculator does not account for.
