A mobile, real-time system for delivering an aerosol spray to a treatment area while maintaining the fluid within a closed environment for providing maximum personal protection to the operators handling the fluid during the transfer and application of the fluid. The invention includes a spraying device for producing a precise degree of liquid droplet generation on a repeatable basis by combining a specified rate of regulated flow of liquid material with a regulated flow of high-pressure air. The delivery system includes a closed loop system for calibrating a liquid pump, which regulates the flow of liquid within the system. A controller is coupled to the components of the delivery system for control thereof. The operator of the delivery system communicates with the controller through a user interface, which provides the operator with manual and automatic controls of the delivery system, such as the closed environment calibration of the pump and transfer of fluid from an external source to the delivery system.

The invention claimed is: 1. A method for calibrating a pump in a closed system, the method comprising: providing a pump in communication with a storage receptacle, a nozzle, a transparent calibration tank, and a valve manifold having a plurality of diverter valves; de-energizing a first diverter valve for establishing a positive liquid flow from said storage receptacle to said pump, through said first diverter valve and then back to said storage receptacle; de-energizing a second diverter valve for diverting said positive liquid flow from said pump to said transparent calibration tank thereby defining a liquid volume therein; maintaining said positive liquid flow to said transparent calibration tank for a time period; energizing said second diverter valve for diverting said positive liquid flow from said pump to said storage receptacle at the end of said time period; reading said liquid volume defined in and visually recognizable through said transparent calibration tank; recording said liquid volume into a user interface; and de-energizing a third diverter valve for diverting said liquid volume from said transparent calibration tank to said pump. 2. The method according to claim 1, wherein said method further comprising the step of: energizing said third diverter valve for diverting said positive liquid flow from said storage receptacle to said pump. 3. The method according to claim 2, wherein said method further comprising the step of: energizing said first diverter valve for diverting said positive liquid flow from said pump to said nozzle. 4. The method according to claim 1, wherein said liquid reading step including visually sensing an amount of liquid delivered to said transparent cylinder from said storage receptacle. 5. The method according to claim 1, wherein said plurality of diverter valves are 3-way diverter spool valves.
