I'm looking for a flow meter to install in our solar loop. I don't need anything fancy. High temp rating, ideally 3/4" copper connection, low flow (1-4 gpm) scale and ok to use in a glycol system. There must be something better than this
This Caleffi flow meter is more in my price range, but I believe that this is designed to attach to a Caleffi manifold so the fitting on one end would be odd. Is there a way to adapt to copper? Also, the temp range isn't listed.
