PURPOSE:To make a monitor installable so easily, by making it up with an inserter inserting a passer, which is installed in a base at the feed side and emits a sound, into a pipe, a recoverer being installed the base at the receiving side, and a sound collector group. CONSTITUTION:A passer 9 being inserted into a pipe line 3 and fed in an arrow direction together with a fluid under pressure is passing through each setup point of sound collectors 8 in regular sequence unless there are clogging and damage 20 in the pipe line 3. At this time, a signal of the passing sound that each of sound collectors 81, 82, 83...8n is amplified at an amplifier 12, then converted into a waveform at a transducer 15, counting it with a counter 16, and when the value is indicated by an indicator 17, what number of the sound collector 8X is passing now is distinguishable. If there were clogging and the like in the midway, the passer 9 comes to be stopped at that point so that what section is a occurring point of trouble is found out. |
