The John Blue VisaGage II Electronic Liquid Blockage Monitor is an automatic warning system that alerts an operator when the flow of liquid on a particular row has dropped below a user pre-selected level. The system uses balls in the VisaGage II flow monitor to determine if the liquid is flowing at the proper level. When a low-ball position has been detected, visual and audible alarms alert the user. Each row with a low ball is highlighted by an LED located in the sensor assembly for locating and troubleshooting the blockage. The system uses a sensor assembly mounted behind the VisaGage II flow monitor to track where the magnetic balls are floating in each row during liquid application. The Premium system has one sensor assembly with a wireless radio that communicates with an iPad in the cab using the manufacturer's free app, while the Standard system uses a wired control panel. Both systems allow the user to select the level at which the alarm will sound and can be paused to capture troublesome rows for identification later.

4-row modules are available and multiple modules can be connected together to obtain sufficient flow monitors for each row of your planter or sprayer. Single modules are also available. A set of magnetic balls comes with each row monitor - the correct ball is chosen based on the flow, which allows the monitor to be used with multiple types of chemicals.
