Abstract
PURPOSE: To provide the flow meter having excellent mechanical strength and little dirt due to dust by a method wherein within a housing fitted to the outside wall wall surface of a main path, a hot wire resistor body, resistor body for temperature correction, a substrate for an electronic circuit and a flow path are installed in one body.
CONSTITUTION: The housing 22 is fitted to the outer wall surface of the main path 12 of cylindrical shape through which a fluid to be detected flows. Within the housing 22, the flow path 28 is installed, which communicates to pick up paths 24, 26 and the fluid to be detected bypasses through. Within the flow path 28, the hot wire resistor body 32 and the resistor body 34 for temperature correction are supported and fixed with terminals 36. On the upper part of the flow path 28, the substrate 40 in which an electronic circuit is installed is fitted. And therewith, an impact flow is eased with the flow path 28, as a result, the mechanical strength of the resistor body 31 against the impact flow increases. And further, some of the fluid to be detected flows into the flow path 28, thus resulting in reduction of dirt of the resistor body 32 due to dust.
