The measuring body (2) has a base body (4), in which a flow channel (6) is formed for connecting a compressed air source with a measurement nozzle, and another flow channel (18,18') is formed for connecting a constricting area with a transducer. The base body is formed to be divided in the axial direction in the constricting area. The latter flow channel communicates with the former flow channel through an annular space (26). The base body has two portions (20,22), and the annular space is formed in the axial direction between the portions. |
