Abstract: <P>PROBLEM TO BE SOLVED: To provide a flow-measuring device 1 of high measurement precision, capable of reducing over-measurement on the occurrence of the counter flow and under-measurement during state of the following current, at a moderate price.  <P>SOLUTION: A bypass passage 7, formed on a sensor body 3 of the flow measuring device 1, includes a U-turn section 7c where flow direction of air changes 180° between an entrance 7a and an exit 7b and an inflow passage 7d of the upstream side, and an outflow passage 7e of the U-turn section 7c is divided off by a center wall 8. On the lateral surface of body at the side of the outflow passage 7e, however, a slit 9 (or window) is opened at the side of the exit 7b closer to the center wall 8. Thereby, when the counter flow generates inside of the outlet pipe 2, a pressure cooker surface 8a of the center wall 8 is loaded by dynamic pressure of the counter flow but dynamic pressure is let out from the slit 9, formed on lateral surface of the body to out of passage. As a result, invasion of the counter flow can be constrained into interior portion of the bypass passage 7 to protect over-measurement attributed to measurement of the counter flow.  <P>COPYRIGHT: (C)2008,JPO&INPIT
