ABSTRACT:
A flow rate detecting device which includes a fixed rotating member for converting a fluid from a straightforward flow to a rotary flow, and a spherical member. Frictional force acting on the spherical member can be decreased and the rotary orbital track for the spherical member can be stabilized by the arrangement of a spherical member receiver, by which the spherical member is supported, having a receiving face perpendicular to the fluid flow, and outflow paths at its central and circumferential sides, and as a result, a high performance of the flow rate detecting device can be accomplished.
