- 09:35, 27 March 2022 diff hist +476 N Water level measurement Created page with "==== 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."

- 07:05, 27 March 2022 diff hist +648 N Refill control for fresh water Created page with "==== Motivation ==== Salt-water aquariums evaporate significant amounts of pure water. The salt contained in the salt-water does not evaporate. If evaporation continues, salinity of the salt-water rises to a level higher than in natural sea-water. Furthermore, cleaning devices like protein skimmers require a nearly constant water-level in the aquarium. The refill control will refill fresh water from a separate tank to the aquarium. * The water level is monitored by mean..."
