Abstract:
1. A vortex flow sensor for measuring a fluid flowing in a pipe, particularly for measuring a flow velocity, a volumetric flow rate, and/or a mass flow rate of the fluid, the vortex flow sensor, comprising: a measuring tube connected into the pipe for conducting the flowing fluid; a bluff body disposed in the lumen of said measuring tube and serving to shed Karman vortices; a vortex sensor device responsive to pressure fluctuations caused by the vortices and to convert pressure fluctuations into an electric vortex signal; and a first temperature sensor being capable of following temperature changes of the fluid to be measured; and a second temperature sensor, wherein: said first temperature sensor is disposed within said bluff body such that first said temperature sensor is separated from the fluid to be measured, and said second temperature sensor being disposed outside of said measuring tube.
