Monitor Flow Volume Accurately

Easily adapt to your factory or after-market pump system to monitor flow volume for each row. The unique design quickly highlights a plugged orifice or blocked screen as the red ball settle to the bottom of the manifold. Protect your valuable input dollars with accurate fertilizer placement.

Wilger Flow Manifold Kit

Wilger Flow Manifold
Our kit includes flow monitors, orifices, 0-60 pressure gauge, two endcaps, and 1” male pipe thread x 3/4" male hose barb that attaches your pump to the manifold. Hose fittings, connectors and other parts are also available.
A typical 16 row planter has 2 manifolds of 8 (4x4) on each wing which allows for the easiest hose routing with minimum amounts of hose per row. A 24 row has 2 manifolds of 12 (6x6) on each wing. And a 36 row has 3 manifolds of 12 (6x6) one on the wings and 1 in the center.

To place your order contact us and be prepared to answer the following questions to ensure we send you the correct sized orifice:

  • Density per gallon (lbs) of fertilizer (example: 11.7 lbs)
  • Average speed
  • Planter size (number of rows & row spacing)
  • Average rate of fertilizer (example: 6 gal)
  • Size of hose running to the row units - we recommend 3/8 outside diameter as it produces less line pressure on cold spring mornings, outside diameter of 1/4 is also typical
