The invention discloses a switchable flow calibration device which comprises an S-shaped pipe, a flow divider and a rotating body. A connecting opening is formed in the top end of the rotating body; awater inlet is formed in the top end of the connecting port; a guide hole is formed in the bottom end of the interior of the rotating body, a sliding groove is formed in the outer side of the rotating body, a pointer is installed on the outer side of the rotating body, an annular support is arranged in the sliding groove, a flow dividing body is installed at the bottom end of the annular support,and a second drain hole is formed in one end of the interior of the flow dividing body. According to the invention, the diversion body, the rotating body, the second drain hole and the guide hole aremutually matched for use; when the flow speed of fluid flowing into the device needs to be regulated and controlled, the through hole diameter of the fluid flowing into the device can be adjusted byrotating the rotating body a
