Application of Phase Doppler Particle Analyser in Agricultural Sprays

摘要：

The basic structure and measurement principle of Phase Doppler Particle Analyzer (PDPA)were introduced. Relative measurement errors were analyzed. And the system was utilized to test agricultural sprays with applied voltage and not. It is indicated that PDPA measurement system has great advantages in the agricultural sprays test compared to other non-contact measurement instruments. The main movement patterns of spray field at different test conditions were analyzed and reviewed conveniently by the system. Spray angle can be measured directly with high precision. Visual distribution of droplet numbers is helpful to design of related equipments and performance predictions.
