Development of the Torque Detected Type Flowmeter Utilizing Lateral Flow Force

A unique flowmeter has been already proposed by the authors. It utilizes the lateral flow force generated on a plate, which is placed in a rectangular flow channel. In the previous works, the test flowmeter was investigated experimentally to clarify the torque versus flow characteristics. Although the results showed good performance in terms of linearity and repeatability, the deviation between the experimental and analytical results occurred on the high flow rate condition. In this report, in order to improve the performance of the proposed flowmeter, the revised configuration of the flowmeter is proposed. Various experimentally investigations are carried out to verify the performance of the proposed flowmeter.
