"Get those home-brew volumes precise. Bundle this with the power supply, flow sensor, and solenoid."
Using this in my home-brew setup to measure the exact amount added to the mash tun and then shutoff using the Digiten 1/2" DC12V normally closed solenoid. Remember to buy the Digiten power supply (required, not included) unless you want to rewire the DC24V +-8V/1A connector. Works exactly as expected, right out of the box. I found the default "K" constant a bit high for my 1/2" silicon tubing and the instructions make reasonably clear sense about changing it (go to that screen, enter the password, then you can change "K") - in my case, changing it from 7.5lpm to 6.5 was about right. Attaching the instruction sheet because it is difficult to find elsewhere.
