Flow sensor

Image Number 11 for United States Patent #5722288.

Disclosed is a flow sensor for sensing heat transfer with a high-speed response, which is manufactured by applying IC micro-machining technology, and which attains an improved heat transfer efficiency by controlling the flow's direction between a heating portion and a sensing portion or by utilizing the intrinsic characteristics of the gas flow.A flow sensor having a substrate whereon a heating portion and a sensing portion are formed each in the form of a bridge supported at both ends or at one end in said order in the direction of the flowing gas to be measured, and which is placed, its surface with the elements down, at the upper inside wall of a pipe for gas to be measured. Its output signal is taken out through lead wires.
