Abstract
A flowmeter particularly for use in determining fluid velocity in oil wells where a torque impeller is connected to a torque force transducer through a torque shaft and a torque coupler. The torque coupler provides for frictionless transfer of torque forces to the torque shaft by torsion bar members. By combining a torque flow meter and a spinner flowmeter means flow can be determined.
