I have purchased one of @BrunDog volume sensors. Per his warning, it puts out 5v and the Uniflex input wants max 3.3v. So, I need a little volt divider circuit that will include a 1kohm resistor and a 2kohm resistor. Apparently these things come in 1/4 watt, 1/2 watt, 1 watt versions. Anyone know which of those I am going to need?
Also, Pete's web page does not indicate the wiring for the volume sensor. Does anyone have one of these? Is it power in, variable voltage out (the volume indicator), and ground? If so, what power does it need? I have an external 24v power source that I am using to power a proportional automatic ball valve. Can I also direct that to the pressure sensor?
Sorry if some of these questions are non-sensical. I am pretty novice with circuits.
