This article describes the measurement system designed in order to determine the metrological properties of air gauges. The said scientific study makes it possible to determine the static pk = f(s) and flow qv = f(s) characteristics. It consists of three modules: a mechanical module, a control and register data module and a special software module. Apart from the possibility of determining the static and flow characteristics, the presented study makes it possible to measure the temperature in the duct that supplies the compressed air to the transducer as well as in the measuring chamber. The above-mentioned measurement system makes it possible to determine the pressure applied on the surface measured by an air stream coming from the nozzle. Apart from a detailed description of a test station and the software, the article also contains sample results of tests performed on air gauges.
