Abstract
An outlet port in the upper end of a fluid flow passageway vertically formed in a flow rate measuring section () disposed in a fluid storage recess () communicating with a fluid inlet pipe through an opening () communicates with a fluid outlet pipe () through an opening (). The heat type flow rate sensor () disposed in the flow rate measuring section () has a fin plate projecting into the fluid flow passageway through a sensor mount hole (). The flow rate measuring section () is formed with an auxiliary flow passageway for leading the fluid within the fluid storage recess () to the inlet port () in the lower end of the fluid flow passageway, the auxiliary flow passageway extending in parallel with the fluid flow passageway and having fluid introducing ports () and a fluid delivering port () leading to the fluid flow passageway. The flow rate measuring section () is equipped with a bottom plate () forming a communication passageway extending from the fluid delivering port () to the fluid flow passageway inlet port ().
