Water level measurement

Motivation

The measured water level is input for the calculation of the refill tank content. In order not to contaminate the water, a contact-less measurement is preferred.

Implementation

The control system uses a device which generates an ultrasonic sound and measures when the sound wave has travelled back from the water surface. The SW system will record the time used for this travel and calculate the corresponding distance using the speed of sound.
