What is out there in the flow switch world that does not have a lot of pressure drop. I've only used the McDonnel Miller paddle type before and hope to find something a bit more...refined. Oh, refined and inexpensive;)

I am Not sure I've ever seen a pressure drop reading on a flow switch with a paddle.
Taco makes a flow switch with a paddle but as far as I remember they are pretty much the same device different colors and nuances to its construction is all.0 -

Harwil built a .5 gpm for me to try, works fine right down to a small lab flow. Labeled as a Q12N C2

HR...You are the man! Thanks! I think for my purposes I will use the 112 model. It has the controller mounted. The Harwil folks were very responsive and helpful.0
