The controller has the pressure probes (2, 3) with the openings (4) located inside the channel. The first pressure probe (2) is located on the leading side of a blade (1) at the rear thereof; the second pressure probe (3) is located on the opposite side of the blade (1) at its front. The pressure probes (2, 3) are connected by means of hoses to an element for pressures difference measurement, which is located on the outside of the duct. The openings (4) of the two pressure probes (2, 3) are oriented parallel to the surface of the blade (1) and directed each other toward the axis (7) of the blade (1). The position of the openings (4) of the first and second pressure probes (2, 3) is defined by the first and the second rectangles (8, 9) of the effective position, which determine the distance of the opening (4) from the edge of the blade (1) and also from the plane of the blade (1) and which are located in the longitudinal axis of the channel perpendicular to the axis of rotation of the blade (1). Regulátor má vnútri kanálu umiestnené tlakové sondy (2, 3) s otvormi (4). Prvá tlaková sonda (2) je umiestnená na nábehovej strane listu (1) v jeho zadnej časti, druhá tlaková sonda (3) je umiestnená na protiľahlej strane listu (1) v jeho prednej časti. Tlakové sondy (2, 3) sú pomocou hadíc prepojené s prvkom na hodnotenie rozdielu tlakov, ktorý je umiestnený na vonkajšej strane kanálu. Otvory (4) oboch tlakových sond (2, 3) sú orientované rovnobežne s povrchom listu (1) a smerujú proti sebe na os (7) listu (1), v podstate do stredu listu (1). Umiestnenie otvorov (4) prvej a druhej tlakovej sondy (2, 3) je vymedzené prvým a druhým obdĺžnikom (8, 9) účinnej polohy, ktoré určujú vzdialenosť otvoru (4) od okraja listu (1) a tiež od roviny listu (1) a ktoré sa nachádzajú v pozdĺžnej osovej rovine kanálu, ktorá je kolmá na os otáčania listu (1).
