Tank Calibration

TankCal helps you build and check tank calibration data for sender-based measurement systems. Enter your tank's maximum centimeter and litre values, choose an Ohm step interval, and fill a clear calibration table with measured centimeter and litre points. TankCal calculates percentages automatically and plots the data as live scatter charts, making it easier to spot irregular entries before you save or share a calibration file. The app supports multiple tank profiles, adjustable step counts, quick Ohm-column filling, calibration notes, and JSON import/export for moving calibration data between devices or keeping project records. TankCal is built for technicians, boat owners, builders, and anyone who needs a straightforward way to organize custom tank readings.
