<p>The invention relates to an oscillating jet meter for fluids, with an assembly in which are formed substantially the chambers and passages of the flow system conveying the fluid, and wherein the inlet and outlet openings of the flow system are in communication with respective pipe connections for the installation of the meter. An oscillating fluid jet is generated in the flow system, the frequency of which within the designated measurement range is at least approximately proportional to the flow velocity of the fluid and which is measured with a measuring instrument so as to determine the throughflow of the fluid in a calculating unit. The aforementioned assembly is in the form of a housing which is closed, except for the inlet and outlet openings, whereas the housing is surrounded on all sides by a pressure-tight casing which carries the two pipe connections.</p> |
