As I'm building the control box for my electric brew system, I'm thinking of adding a flow meter. My plan is to use a couple of wifi thermostats and series of relays and contactors so that I can begin brewing from my phone an hour or two before I even get home from work. Once I get it wired in, with a couple of taps on my phone and the solenoid wired into the flow meter opens to allow my strike water to fill my HLT. I have not sourced it yet, but I know it has to exist somewhere, I'll a wet switch set just and inch or so above my heating element. as soon as that trips, the element turns on and begins heating the strike water and then when the preset amount has passed the flow meter, the solenoid closes. So, by the time I get home, my strike water will be heated and ready for doe in.
depending how long it takes to heat, I will have the same set up wired into another kettle set to come on a half hour or so after my strike water. So, by the time I get home, doe in, and do a 60 min mash, my sparge water will be ready. All from just a few taps on my phone.
Questions? Comments? Rude remarks?
This is the flow meter I'm looking at. https://www.amazon.com/dp/B00YPA6XBG/ref=wl_it_dp_o_pC_S_ttl?_encoding=UTF8&colid=1VFZTH2M8W67T&coliid=I1NXDMOLV0A3JO
