Abstract
A valve control system for a compressed air foam generation apparatus includes a control board with a scrolling light display to indicate the quality of foam being produced. The control board is coupled to a manually operated valve by a string potentiometer. The string potentiometer connects at a ring coupled to the valve, such that turning of the valve causes the string potentiometer cable to extend or retract, thereby indicating the degree to which the solution valve is opened.
