Abstract

PURPOSE:To permit easy searching from remote plates by feeding fluids forcibly into a piping, feeding said fluids to the water leaking point of the piping and searching the ejecting sounds from the leaking point acoustically. CONSTITUTION:When mixed fluids of gas and water mixed in a mixer 6 of a force feeder 1 are fed forcibly into a water supply piping 16 by a pressurizing pump 5, the mixed fluids arrives at a leaking point 34 while they are gradually separated to gas and water, from where the fluids eject and generate unique bursting sounds. The operator moves a searcher 22 on the ground, ampifier 26 the sounds received in a microphone 23, and hears the sounds with a headphone 28, thereby searching the point where the bursting sounds are generated. Since the bursting sounds are of extraneous tone quality, the leaking point is searched easily with the microphone 23 from remote places.
