Hi all,
I'm seeking recommendations for devices that can measure flow rate (i.e., in-line flow meter) that can handle the glycol solution and 180 deg F temperatures in a solar thermal closed loop. I've got a nice solar thermal system that's been working fine for 6+ years (2 Steibel Eltron Sol 25 Plus collectors on the roof and a SBB-300 Plus tank in the basement). I've got it wired so I can monitor temperatures in all parts of the system, and now I'm interested in monitoring flow rate through the closed loop. A device that outputs a digital pulse would be ideal. Any suggestions? Thanks
