<p>Coriolis-principle mass flow meter has an impeller that is driven at constant speed and subjected to a material flow. The torque of the wheel is measured to determine the mass flow. The impeller (2) is suspended on a torsion spring rod (7) that is mounted within a hollow axle (6). The impeller is driven by the torsion spring rod. At least a sensor (8, 10) measures the angular displacement between the driving hollow axle and the impeller.</p> |
