Someone asked me if I could design an Arduino based system to measure the flow rate of a water pump in a fish tank.
I have zero experience with any kind of fish tank. I would imagine a flow sensor would just go inline with the output of the pump, which is easy enough. But, some questions arise...
Is there a standard size hose that would be compatible with a sensor?
Is there a particular type of sensor that is better suited for the "fish" environment? I know some species are very "delicate" when it comes to, well, anything (had a friend lose an entire tank in under 12 hours once because something foreign was introduced- I don't want to be in that boat).
Water is a nasty environment... do these things get clogged or have to be cleaned occasionally? Last thing I would want is a clogged flow sensor blocking the output of the pump.
Is there a sensor that is more "industrial" that will work with Arduino? The ones I'm seeing are all part of experimenter kits and look pretty flimsy. For a prototype or proof of concept they look fine, but for something that has to perform for months or years at a time...
