Wilger ORSM Metering Orifice w/ FKM O'Ring #11| 21011-00

Wilger ORS manifolds make it even easier and cost effective to setup and manage liquid applications.

Precise metering orifices for metering liquid fertilizers, or chemicals. The easier-to-handle orifices fit in any O-ring seal (ORS-M) fitting port, and cannot be inserted backwards. 

Calculating required flow for metering orifice selection: 

To determine the flow rate (or application rate), use the following equations & density conversion chart.

W = Outlet Spacing (INCH)

conv = Conversion Factor based on specific gravity/weight of liquid

GPM (per outlet)= GPA x mph x W x conv / 5940

GPA = 5940 x GPM (per outlet) / mph x W x conv
