Abstract:
A thermo-sensitive flow rate sensor comprising:a flow rate detecting device having a plurality of flow rate detecting diaphragms thereon, each flow rate detecting diaphragm provided with heating portions and temperature detecting portions thereon,wherein said plurality of flow rate detecting diaphragms are arranged in a direction perpendicular to a direction of flow of a fluid to be measured,wherein each of said flow rate detecting diaphragms is formed and placed so that a length of a longer side thereof is at least two times a length of a shorter side, and wherein the longer side thereof extends along the direction of flow of the fluid to be measured, andwherein each of said flow rate detecting diaphragms has at least one of said heating portions and at least one of said temperature detecting portions, said heating portions and said temperature portions being arranged along a direction of flow of said fluid to be measured.
