ABSTRACT:
A transducer for a vortex flowmeter is used for the volume flow measurement of gaseous, liquid and vaporous media. In order to provide a particularly robust transducer for vortex flowmeters, which is suitable for high and low flow rates of gases, vapours and liquids with high and in particular low densities and is also suitable at high temperatures and high pressures and in the case of contaminated media with a high measurement sensitivity and optimum signal detection, a one-piece vortex body with a sensor integrated therein is to be used. The one-piece, triangular or trapezoidal vortex body is provided with vertical recesses in the vicinity of its tapering side walls, so as to form a compact vortex generation area, a vortex determination area and a vortex detection area as the minimum rigidity area.
