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