A measuring, computing and recording system for real-time monitoring of spray application parameters for pesticides and the like, dispensed from aircraft. The system includes means for measuring, computing and recording (1) total liquid volume, (2) liquid pressure, (3) liquid flow rate, (4) total spray passes, and (5) total spray time. The system also includes means for measuring and recording relative humidity, air temperature, and dispensed liquid temperature. A spray pressure exceeding a predetermined pressure set point is required to initiate and maintain the flow rate computing and associated recording operations of thesystem. The measuring and recording of relative humidity, air temperature and dispensed liquid temperature may be independently controlled if so desired.
