So today I've been trying to brainstorm a way to implement a proportional electronic valve for flow control at the outlet of my march pump (to automate matching flow rates for the brutus 20 style CRDFM method), and it just occurred to me that it may make sense to throttle the pump itself via electronic means (something like a router speed control, but with electronic input rather than a knob)
I am sure you would not get a nice simple linear response, but I wonder if it would be good enough to be useful... For something like matching flow rates, you don't need control of the full range from 0-100% of max output - a significantly smaller portion of that range could be good enough.
I wish I had a router speed control lying around to test the idea. I'd go grab a lamp dimmer if I didn't think it would be likely to go up in smoke when used with a motor...
Anyone ever try anything like this?
