Abstract
PURPOSE: To easily measure the flow rate of a gas flowing in a corrugated pipe, by providing the corrugated pipe with an acoustic magnifying and emanating horn, and determining the frequency of sounds occurring in the horn.
CONSTITUTION: An acoustic magnifying and amanating horn 8 is provided on a corrugated pipe 7 in which a gas flows. When a gas flows in the corrugated pipe 7, a fluctuating pressure wave having loops inside ridges of the corrugated pipe is formed. A frequency (f) of this fluctuating pressure wave, a velocity of flow V(m/ sec) of a gas and the number B of ridges per 1m of a corrugated pipe have the relation expressed by a formula V=2f/B. Accordingly, when the frequency (f) of the fluctuating pressure wave is received by microphone 9 so as to be measured through a frequency analyzer 10, the velocity of flow of the gas flowing in the corrugated pipe can be determined.
