US Patent 10539480 Frequency sub-band leak detection

Examples of analyzing data for a distribution pipe network within a fluid distribution system are disclosed. In one example implementation according to aspects of the present disclosure, a method for analyzing data for a distribution pipe network within a fluid distribution system includes: receiving acoustic data from a plurality of nodes for a plurality of pipe segments; determining a characteristic frequency range for each pipe segment; decomposing the characteristic frequency range into a plurality of frequency sub-bands; building a leak sensitivity model based on the plurality of frequency sub-bands; and implementing a correlation schedule with the plurality of nodes based on a selection of the plurality of frequency sub-bands.
