Abstract

A hot-wire type flow velocity meter having a heat generating electric resistor and a supporting member for supporting the electric resistor. Shielding means are provided to shield the supporting member to prevent the change of heat transfer from the supporting portion to the fluid around the supporting portion due to a change in the flow velocity, thereby to eliminate the error in the flow velocity measurement.
