Nozzle selection via characteristic curves

Nozzles of a particular type and size can be selected from characteristic curves with allowance for the desired forward speed according to the following criteria:

• Application rate (l/ha)
• desired atomization characteristic for the product employed and crop concerned

The atomizing characteristics of Lechler nozzles build on their droplet size data and their classification according to categories defined by BCPC (British Crop Protection Council). Lechler's droplet-size analyses are conducted according internationally standardized methods using morn phase doppler particle analyzers (PDPA).

This approach yields a complete, type-specific description of each nozzle's pressure-dependent atomization characteristic in terms of droplet size and droplet velocity. The nozzles are assigned to different droplet-size categories (very fine , fine, medium, coarse, very coarse ) formulated on the basis of reference nozzles. This way, different types of nozzles are easier to compare for different spray pressures.
