In my previous post I gave a link to a low cost motorized ball valve from Amazon that looks like it could be used as an adjustable valve. All that is needed then is a flow rate sensor to drive the valve motor (probably with PWM to slow down the adjustment) until you get the flow rate you want. Lots of relatively low cost flow rate sensors seem to be readily available, and would only use one of the sensor pins.
