The recordings are processed to characterize evolving nighttime sound patterns over days and months. The processed patterns are stored in the memory and transmitted by radio on demand. MLOG PC software analyzes all available data from the entire distribution system and assigns each MLOG sensor a leak status.<\/p>\n<p><img src='http:\/\/water-simulation.com\/wsp\/wp-content\/leak_status.jpg' alt='' \/><\/p>\n<p><!--more--><br \/>\n<strong>Leak Index<\/strong><br \/>\nThe <em>Leak Index<\/em> is the signal processing heart of the MLOG system. It is a number from 0 to 100, indicating the probability of a leak present at that MLOG sensor.  <em>Leak Status<\/em> is derived from <em>leak index<\/em> which is computed from:<\/p>\n<ol>\n<li>Recorded historical sound patterns<\/li>\n<li>Analysis of a subset of MLOG sensors, with emphasis on unusual activity.

The MLOG software is able to refine the definition of a leak acoustic signature, improving the accuracy of leak identification, size &#038; type.<\/li>\n<\/ol>\n<p>One  innovation of the MLOG system is the systematic, adaptive approach to characterizing leak vibrations.  The MLOG sensor does not attempt to determine whether a leak is present but instead uses patent-pending signal processing techniques to model the vibration patterns present in its vicinity. <\/p>\n<p><strong>MLOG Color Map\u05d2\u201e\u00a2<\/strong><br \/>\nThe MLOG software provides tools for:<\/p>\n<ul>\n<li>Visualizing leak locations<\/li>\n<li>Printed and electronic reports<\/li>\n<li>Searching and sorting MLOG sensors by leak index, status and other factors<\/li>\n<\/ul>\n<p>The MLOG color map\u05d2\u201e\u00a2 plots the <em>leak index<\/em> over a geographical area, superimposing a solid color map from blue (low leak index) to red (high leak index) on a utility GIS map.<\/p>\n<p><img src='http:\/\/water-simulation.com\/wsp\/wp-content\/leakmap.jpg' alt='' \/> <\/p>\n<p>In the MLOG Color Map above, 2 areas of leakage are discerned.
