I have a fun resi install 120 psi static, 30 gpm at 60psi dynamic. My question is how do you install your flow sensors. I would like to install this next one on unions. Hunter reps have told me this is a bad idea. I can't see any issues with this as the union is full port straight through and a bad glue joint would cause more turbulance. I searched and saw a sensor for calsense on brass unions on a old thread. I will try and post pics next week.
