metering, which is a more complex sensor regarding maintenance
and durability concerns. Second, the water level into the tank could
be performed by means of a complex continuous sensor, or maybe
it could be performed by using some simple on/off sensors (for
example, four on/off sensors on: 10%, 30%, 60% and 99% levels).
Thus, when water level is lower than 10% the controller should
trigger to a “reinforced-production strategy” in which the pulsed
temperature (Tp) should be minimized; on the contrary as much as
the water level increases across intermediate levels the microcontroller
should increase Tp and finally, when the water level overpasses
99% level the microcontroller should trigger to a “non-pulses
strategy” to prevent tank flooding. Following this scheme, to set Tp
within the intermediate range is certainly the most complex algorithm.
This selected temperature should take in account many
variables; just in a first glance we can guest some ideas:
