Flow Monitors

The CDS-John Blue Flow Monitors are perfect for monitoring flow rates when spraying or applying agricultural liquid fertilizer. The VisaGage II is cost effective and simple to install in single columns or in sets of four flow meter assemblies. In addition, most CDS-John Blue Flow Monitor parts are interchangeable with other brands already on the market today.

CDS-John Blue VisaGage II is manufactured with chemical resistant polypropylene adapters and clear PVC body with an additive for UV protection. Viton o-rings are also standard. There are no electronic parts that could potentially fail.

You can now turn your CDS-John Blue VisaGage II into a self-contained orifice changing system. This patent pending system is the first of its kind on the market today. Simply select from one of the four orifice setting on the two discs provided. No more getting wet from fertilizers or chemicals when changing orifices. Adjustment is quick, no need to travel to each row unit and work with plumbing near the ground.
