PLANAR LASER FLOW VISUALIZATION OF A KNAPSACK (BACKPACK) SPRAYER

Within phytosanitary protection procedures, for small agricultural holdings, for gardens and parks, portable sprayers are the preferred application devices. Their large number, along with the non-uniformity of technical or operational parameters, justifies a thorough investigation of them. The present work represents a first step in investigating the guality of the jet produced by a portable sprayer by a simple method, that of visualizing the jet produced by the sprayer nozzle with the help of a laser plane. For this purpose, an investigation method is proposed with components highly available and low costs, respectively, a digital camera and a laser level capable of projecting a laser plane.
