We have free apps for use with John Blue's Liquid Blockage Monitor system. Now you can know your liquid application flow from the cab of your tractor. The patented system alerts you when a ball and flow in an individual row has dropped below a user-selected level in a John Blue VisaGage II Flow Monitor. Two different products may be monitored at the same time, and real-time ball position information is relayed to the user. The system communicates via Wi-Fi with the tablet, which serves as the control panel and display using this app.
