Abstract (en)
[origin: EP2626567A1] The housing has a suction channel (14) led into a chamber (15) for arrangement of a gyro wheel rotated at a rotational axis (5). The suction channel has helical rotating channels (16) opened to the chamber and led into a pressure channel. A sensor channel (22) connects a retainer (20) in a form of hole for a differential pressure sensor, with a suction-side interior of the housing. Another sensor channel (23) connects the retainer with a discharge side interior of the housing. The retainer is arranged between the helical rotating channels and the suction channel.
