Flow velocity measuring device based on Magnus effect, and measuring method thereof

Abstract

The invention discloses a flow velocity measuring device based on a Magnus effect, and a measuring method thereof, and relates to the field of fluid velocity measurement. The flow velocity measuring device comprises a shell and an internally hollow cylinder, wherein one end of the shell is fixedly provided with control equipment, the other end of the shell is open, a direct-current motor connectedwith the control equipment through a fixed bearing is arranged in the shell, one end of the cylinder is fixedly connected with a hard long rod, the end, away from the cylinder, of the hard long rod is fixedly connected with the direct-current motor, and a plurality of pressure sensors are uniformly and annularly arranged on the inner wall of the opening end of the shell and are in stress-free contact with the side wall of the hard long rod. The measuring method based on the device comprises the following steps: 1; determining the overall structure of the measuring device; 2; arranging pressure sensors; 3; calculating cylinder stress according to sensor data; and 4; processing and modifying resulting data. According to the invention, the fluid speed can be measured, the speed direction canbe measured, and the speed measuring device is small, convenient and low in production and maintenance cost.

[0003] There are many methods and instruments for measuring fluid velocity, but each has its own advantages and disadvantages, and there is no fluid velocity measuring device that is completely suitable for various situations

Common flow rate measurement devices such as electromagnetic flow meters are expensive and cannot measure the flow rate of non-conductive substances. Ordinary turbomechanical flow meters have disadvantages such as complex structure, poor accuracy, and relatively bulky structure.

There are also Venturi tube flowmeters and throttling flowmeters, etc., but these flowmeters can only measure the flow rate of the internal flow
