Abstract

PURPOSE: To measure flow rate from the flow speed with frequency analysis for the noise produced when powder steadily flows.
CONSTITUTION: The sound collection unit 2 fitted at the side wall of the flow path 1 collects the noise produced from the object flowing in the flow path 1 and feeds noise signal to the frequency analyzer 3. The unit 3 measures the sound pressure p to each frequency f, and flow speed v is obtained with the operation 4 of the frequency f and sound pressure p, and further, flow is obtained. This flow is displayed with the indicator 5.
