摘要： PROBLEM TO BE SOLVED: To provide a flow measuring device preventing the accumulation of a contaminant on a detecting element and capable of measuring a backflow as well as a forward flow. SOLUTION: A guiding-in port 25 and a guiding-out port 26 opened on planes perpendicular to the flowing direction of a main flow M to be detected are formed face to face at both ends of the outer peripheral section of the outer wall 23 of a branch tube 20. A plurality of branch passages 28a, 28b branched and met in the branch tube 20 are formed by a curved partition 27 in the branch tube 20. Corrugation sections 32, 33 are formed inside both end sections of the outer wall 23 respectively to block the inlet and the outlet of the outer peripheral side branch passage 28a. Contractions are formed on a passage between the guiding-in port 25 and the inlet of the branch passage 28a and a passage between the guiding-out port 26 and the outlet of the branch passage 28a respectively, thus a nearly Q-shaped passage is formed in the branch tube 20. The detecting element 31 is fitted to the bottom section of the outer wall 23 of the branch tube 20 to be exposed to the flow in the outer peripheral side branch passage 28a, and a downflow DW further separated from a devided flow D obliquely collides with its detecting face.
