I have popup fert. setup on my CIH 1200 planter. I had been monitoring it with a microtrac "Spraytrax" but it quit working. Can I set up a flow meter and butterfly valve and connect it to my Pro600 to monitor and control the flow or do I need to get the factory liquid fert. setup that CIH mades for the planters? Don't really want the CHI system, what I have now it a KISS (keep it simple stupid) system and would like to keep it that way.Would just be nice to have one less box in the cab.
