Abstract

A flow medium inlet (5) which can be regulated leads to the cylindrical measurement channel (4) which also has a medium outlet (7). An axially movable piston (8) is located in the channel and is spring-loaded against the incoming flow. It has a central round axial channel or a hole (10). Inside the channel is a regulator piece (11) which is at least movable axially, and has a reducing part (12) in the flow direction for insertion in the central piston hole. The hole and reducing part determine the flow channel through which medium may pass to the outlet on the other side of the piston. The piston movement indicates deviations in flow, and the part (12) with the reducing cross-section is formed by a cylindricaal piece with material removed from its cylindrical surface to make it pref. wedge-shaped. @(Provisional basic advised week (1/50)@ @(7pp Dwg.No.1/2)@.
