Abstract
PURPOSE: To detect a water leakage accurately and early by mounting a sound detector (microphone) properly on each piping.
CONSTITUTION: A sound generated on a piping 1 is collected on a sound detector 4, converted into an electric signal through a sound-current converter 5 and then sent to a waveform converter 7 through a transmission line 6. The waveform converter 7 converts an electric signal converted through the sound-current converter 5 into a rectangular wave. A measuring wave led from the waveform converter 7 and a normal signal with a waveform setter 3 are subjected to comparison on a waveform comparator 9 for height, width and period of each waveform, and the gap is delivered to a discriminator 10. Where the gap between the two exceeds a tolerance, the discriminator 10 lights up an alarm lamp 11 to indicate a water leakage on the piping 1.
