Abstract
A rotation type flow meter comprises a case, a rotation mechanism and a sensor. The rotation mechanism is arranged in a cavity between a flow inlet and a flow outlet of the case, and the sensor is arranged on the case and is adjacent to the rotation mechanism. A flowing-in channel and a flowing-out channel are formed inside the rotation mechanism, the center line of the flowing-in channel coincides with the rotation axis of the rotation mechanism or approximately coincides with the rotation axis of the rotation mechanism, a distance is reserved between the center line of the flowing-out channel and the center line of the flowing-in channel, and the center line of the flowing-out channel and the center line of the flowing-in channel are arranged in different planes. Fluid, flowing through a fluid channel, to be tested drives the rotation mechanism to rotate, the sensor measures the rotation speed of the rotation mechanism, and flow can be obtained by converting the rotation speed. The rotation type flow meter is simple in structure, small in size, low in price, good in durability and reliability, wide in measurement range and easy to install and adjust, and can measure corrosive media. In addition, the rotation type flow meter can measure the mass and the size of the fluid.
