Tank Sensor Calibration Made Simple

A major hassle when calibrating a tank sensor to an external controller is filling and emptying the tank.

This creates many hours hanging about waiting for the correct levels to be obtained before calibration can start.

There are propriety products on the market which will inject a milliamp signal and some instrument engineers keep such products in their tool bag but not all do and they can be expensive. A simple solution would be to have a software facility in the tank sensor that would give the correct calibrated current output at the press of a button. A neat solution which you will find in the MiniSonda ultrasonic transmitter.

Then you can add in the fact that one instrument will cover an operating range from 0.5 metres to 8 metres rather than having to stock two or three different products to cover these ranges plus an instrument that is better than IP67 at all times.
