ABSTRACT:
A method and apparatus for delivering constant water flow rates to the fire hose of a pumper truck at each of a plurality of selectable flow rate settings including the steps of transmitting a digital signal corresponding to a particular fire hose and pumper truck, receiving and decoding the digital signal, activating a multi-position valve in response to the decoded signal to set a particular valve position, and maintaining a constant flow rate to the fire hose by automatically varying the valve position in response to changes in the output pressure of the pump and pressure drop in the fire hose.
