Wilger Flow Indicator - Standard Flow
Flow indicators allow sprayer operators to visually monitor the flow of the system to spray tips and orifices. The floating ball in the indicator body will show if a tip is performing as it should. When operating, the indicator ball will float towards the upper middle section. If a ball is floating lower than those in the other indicators, there is lack of flow due to a blockage in the system. When a ball is floating higher, there is excess flow due to a leak somewhere in the system.
Wilger Part # 20460-00 is the standard flow model. These indicators are rated for .05 to 2.7 GPM.
