I have a rainwater harvesting system with three tanks each with a separate pump. I will have a pressure vessel and pressure switch to automatically start pumping when water is required. However, I do not want to run all three pumps together but one at a time. I need a switch which will ensure all three pumps are used in roughly equal proportions. It seems to me this could be sequential, switching to each pump in turn or completely random i.e. starting a different pump randomly each time.
Does such a switch exist and if so what is its technical name? Any suggestions - other than changing configuration of tanks and pumps which cannot be done!
thanks
