Acoustic Leak Detector
US Patent:
4327576, May 4, 1982
Filed:
May 5, 1980
Appl. No.:
6/146984
Inventors:
Joseph W. Dickey - Annapolis MD
Paul M. Moore - Gaithersburg MD
Lloyd E. Powell - Annapolis MD

Assignee:
The United States of America as represented by the Secretary of the Navy - Washington DC
International Classification:
G01M 308
US Classification:
73 405A
Abstract:
The invention relates to a leak detecting device for pipe systems having electronic channels for processing the acoustical signals from the source of the leak to determine the direction of propagation of the leak signal. Each channel includes a transducer, an amplifier unit, a variable delay unit for delaying the transmission of signals received from the amplifier unit, and a multiple-averager unit which respectively multiplies and then averages input signals from the variable delay unit of the same channel and, depending on the mode of operation, from the amplifier unit of either the same or the other channel. Operating in a first mode to determine the frequency and wavelength of the primary leak signal, the signals from the variable delay unit of one channel are combined with the signals from the amplifier unit of the same channel in the multiplier-averager unit. Upon determining the wavelength of the primary leak signal, the transducers are spaced apart by about one-quarter of such wavelength and attached to the pipe. Operating then in a second mode to determine the direction of propagation of the acoustical leak signal, the multiplier-averager unit of one channel receives signals from the variable delay unit of the same channel and the amplifier unit of the other channel.

International Classification:
H04B 100, G09B 900
US Classification:
367131
Abstract:
An array of piezoelectric transducers from which acoustical energy is emid at a low and high frequency within a predetermined frequency band, synthesizes a localized underwater simulation of a remotely located explosion pressure field, by programmed computer control over the electrical energy input from a signal frequency generator transmitted through power transfer circuitry to the array of acoustic projecting transducers.
