Wilger Flow Manifolds

Easily adapt to your factory or after market pump system to monitor flow volume to each row. A plugged orifice or blocked screen makes the ball settle to the bottom of the manifold to insure correct placement of your valuable input dollars. Kit includes Flow monitors, orifice's, pressure gauge and 3/4" male hose barb connection fitting.

Hose fittings, connectors and other parts also available. Please call us with any of your flow and plumbing related issues.

Typical 16 row planter would have 2 manifolds of 8 (4x4) on each wing. This allows for easiest hose routing with minimum amounts of hose per row.
24 row would have 2 manifolds of 12 (6x6) on each wing.
36 row would have 3 manifolds of 12 (6x6) one on the wings and 1 in the center.

In order to make sure we send you the correctly sized orifice, please answer these questions.

1. Density per gallon (lbs) of fertilizer (for example 11.7 lbs)
2. Average Speed
3. Planter size (number of rows & row spacing)
4. Average rate of Fertilizer (for example 6 gal)
5. What size of hose will be running to the row units? We recommend 3/8ths OD (Less line pressure on cold spring mornings). Most typical will be ¼ OD. (OD- outside diameter; ID- inside diameter)
