EN The article presents the basics of the Particle Image Velocimetry (PIV) measurement method, a non-invasive technique for determining fluid velocity fields, and the designed and constructed universal PIV digital imaging anemometry stand and its possible applications. It can be widely used, both in industry and in scientific laboratory research. The PIV method is used in many areas, e.g., in gas and fluid flows, combustion studies, and machining processes. The PIV measuring installation with the elements designed in AutoCad 2019 by AutoDesk is showed. The stand consists of a tank, LED lamps, pumps, a special nozzle, a camera, and a PC with PIVlab software. Both pumps are equipped with controllers. The obtained results allow for identifying zones where there is no fluid movement or places where particles move at low speeds. The preliminary conditions for research and analysis have been defined. The designed and constructed stand is undoubtedly suitable for research work related to the flow on a laboratory scale. PIV can be successfully used to describe the process of liquid spraying, spray drying, granulation and grinding, mixing and separation, heat and mass transfer.
