Abstract

PURPOSE: To eliminate the formation of an opening to a gas supply pipe and to substantially dispense with attachment parts, by securing one end of a tongue piece to the predetermined position in the gas supply pipe to vibrate the same in correspondence to the flow rate of gas and detecting said flow rate through the detection of vibration.
CONSTITUTION: A tongue piece 2 is attached to the inner surface of a gas supply pipe 1 and a vibration detection means 3, for example, a condenser microphone is attached to the outer surface of said gas supply pipe 1 corresponding to the part, where said tongue piece 2 is attached, in order to detect the vibration of said tongue piece 2. The tongue piece 2 is formed of a thin plate comprising a material receiving no corrosion by gas and attached to the gas supply pipe 1 so as to be inclined at a predetermined angle toward the flow direction X of the gas. Because the vibration frequency of the tongue piece 2 and the flow rate of the gas have relative relation, by detecting the vibration frequency of the tongue piece 2 vibrated corresponding to the flow rate of gas, the flow rate of the gas can be detected.
