APPARATUS FOR MEASURING FLOW RATE OF LIQUID BY A RADIOSCOPY AND METHOD THEREOF

摘要

A flow rate measuring apparatus and method using radioscopy are provided to block leakage of a fluid using welding and prevent generation of cross or error in electric signals caused by impurities on electrodes. A flow rate measuring apparatus(1) includes a displacement sensor(3) having displacement according to flux of a target fluid flowing through a pipe(2), a radioscopy(4) for irradiating radioactive rays to the displacement sensor, a radiation sensor(5) for sensing the radioactive rays which have passed through the displacement sensor to detect displacement, a signal input/output and conversion unit for converting the detected displacement into a flow rate, and a monitor(7) for displaying the flow rate.
