This version of the FlowMeterPanel is professionally powder coated white and has a three week lead-time from order to delivery to your location. The Redball liquid flow monitors on our planter have always presented a challenge: the dark liquid fertilizer makes it difficult to see the balls inside. That’s where FlowMeterPanels come in—they provide a bright, uniform background behind the monitors, simplifying the task of checking the row-by-row status. FlowMeterPanels are tailored to fit the original Redball flow monitors from Willmar Manufacturing and are also fully compatible with John Blue VisaGage II flow monitors. FlowMeterPanels come in four sizes — 4, 6, 8, and 12-row flow meter configurations. This listing is for the 4-row FlowMeterPanel version. Made in the US from durable American 5052 aluminum, FlowMeterPanels are built to endure for years. Backed by our straightforward warranty, they deliver the reliable quality you expect from all our products.
