Patent ID: 7726187

Claim:
A heating resistor type flow rate measuring apparatus comprising: a first heating resistor arranged in a passage; a support member projecting from a console for supporting said first heating resistor and said support member includes a plurality of lead line members; a second heating resistor connected to said support member; temperature detection means including a temperature measuring resistor connected to said plurality of lead line members and interposed between said first heating resistor and said second heating resistor; and control means for controlling heat generation by said second heating resistor such that temperatures detected by said temperature detection means fall into a predetermined temperature range inclusive of temperatures of said first heating resistor, wherein each of said first heating resistor, said second heating resistor, and said temperature measuring resistor is electrically connected to said plurality of lead line members, and wherein the temperature measuring resistor is arranged between the first heating resistor and the second heating resistor, with the first heating resistor mounted adjacent a top of said support member and said second heating resistor is disposed adjacent said console.
