Wilger Flow Indicator - Low Flow

Flow indicators allow sprayer operators to visually monitor the flow of the system to spray tips and orifices. The floating balls 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 of the tube. If a ball is floating lower than another, there is lack of flow due to a blockage in the system. When a ball is floating higher than others, there is excess flow due to a leak somewhere in the system. Wilger Part # 20470-00 is the low flow model. These indicators are rated for .03 to .7 GPM.
