Abstract

What is proposed is a probe for measuring the dynamic pressure of a fluid flowing in a pipe, which is insensitive to impurities carried along by the flow medium and which ensures a uniformly low measuring error over a period of years. The probe according to the invention has at least one receiving tube extending transversely relative to the direction of flow of the fluid and possessing at least one pressure pick-up orifice, the perpendicular of which is directed parallel to the direction of flow, and to achieve the object is so designed that the pressure pick-up orifice (8, 8a) is a single slit (8, 8a) extending over most of the pipe in its longitudinal direction. <IMAGE>
