摘要
A butterfly valve having a function for measuring a flow rate of a fluid flowing through the butterfly valve includes a main body (1), a valve shaft (3) fixed rotatably to the main body (1), a valve member (2) fixed to the valve shaft (3) and mounted rotatably in the main body (1), a valve opening detection device for detecting a valve opening of the butterfly valve, and a torque detection device (12) for detecting a dynamic torque applied to the valve member (2) around the valve shaft (3) by the fluid.
