I am installing a peristaltic metering pump in our greenhouse water system with a chemical to reduce scale build up. The proportional pump system will get a signal from a water meter for every quart that passes by, and a dose of juice will go in to a 3/4" line which then tees off about 4 feet away. Flow can be less than 1 gpm up to 20gpm. Mix rate is around 1:5,000.

I am concerned that the fluid won't be completely mixed before teeing off to go to different places. The company says it should work.

Can someone explain how this mixing works. I considered a static mixer or some kind of "mix chamber", but they said it was not needed. Doesn't water flow kind of "laminaer" in pipes without any mixing?

Thank you.
