Abstract

The invention relates to an impeller torque measuring device for a measuring device in which the mass flow rate, in particular of a bulk material or a fluid, is measured by using the Coriolis measuring principle, comprising an impeller (1) mounted for rotation on a vertical shaft (2) driven by a motor (3), the impeller (1) mounted on one end of the shaft (2) and the motor (3) on the other end of the shaft (2), and wherein the mass flow is charged into the central area of the rotating impeller (1) on which the mass is radially directed to leave the rotating impeller (1) over its circumferential edge, and wherein the torque necessary for rotating the impeller is measured by a torque measuring device (4). The shaft (2) and the motor (3) are connected to a stand (14, 15, 16) supporting the impeller torque measuring device by means of the torque measuring device (4) measuring the torque exerted by the motor (3).
