AGRICULTURAL SPRAYER TEST RIG PATTERNATOR

MECHANICAL SPRAY PATTERNATOR FOR NOZZLE TESTING:

Mechanical Patternator setup used to evaluate the liquid distribution provided by a nozzle, or array of nozzles.

Typical mechanical patternators collect the sprayed material at many locations across the spray plume and the level of each collection bin is recorded.

These instruments are very useful for quickly and accurately assessing the spray distribution change with different nozzle types/capacities, operating conditions, spray distances, and nozzle spacing.

Mechanical patternators are being used to assess the spray centre-line, cross-sectional distribution, or the collapsed 1D distribution of a spray; both manual,

automated, and image-based systems are used to record the distribution data.
