<p>The invention relates to a turbulent flow meter (1) for measuring the mass flow rate, the volumetric flow rate, or the flow rate of a fluid, which flows in a measuring tube (2) that has a tube wall (21). Said meter has a temperature sensor (34), which is positioned in such a way that the turbulent flow meter can also be used with fluids that are corrosive to the temperature sensor. A resistance body (4), which creates turbulence and thus pressure fluctuations, is located in the measuring tube. A turbulence sensor (3), which responds to said body, is inserted in a bore (22) of the tube wall (21) of the measuring tube, downstream of the resistance body. The turbulence sensor (3) comprises a membrane (33) that covers the bore (22), a sensor vane (31) that projects into the fluid being fixed to said membrane. The temperature sensor (34) is fixed in a blind bore (314) of the sensor vane on the base of said bore. A sensor element (35) is fixed on the opposite side of the membrane from the sensor vane. Alternatively, the temperature sensor can be located in a longitudinal bore (24) of the resistance body.</p> |
