 brochures : read more about MLOG - network of intelligent, water leak sound detecting sensors which monitor the entire water distribution system. Every night MLOG water leak noise sound detection sensors analyze sound patterns in their environment, detecting new leak noise, evolving water leaks, and preexisting water leaks automatically. MLOG water leak noise sound detection sensors are maintenance-free. The units are rugged, waterproof, and battery-powered (10-year life). They are installed either indoors or outdoors on a water service pipe, usually near a water meter

MLOG is a network of intelligent leak detecting sensors which monitor the entire water distribution system 365 days a year

The first complete solution to water loss detection and pileline integrity survey in every street and home

  • World′s first truly permanent, automatic leak detection system
  • Round-the-clock secure monitoring of the water distribution system
  • Comprehensive, distribution system-wide information at your fingertips
  • Affordable, cost effective, maintenance-free service
 mlog system brocures: water leak noise sound detection sensors analyze and save vibration patterns from the water distribution system, using advanced digital signal processing to characterize water leak sound patterns in the underground pipes over survey time; managing water loss using acoustic sensors and advanced wireless communications with both the amr and controller approaches to data collection, information from thousands of mlog sensors is brought to the utility manager´s desktop every morning. the mlog system can leverage the investment in amr, often pay for itself within 2 years of a specified 15-year operating life. mlog is an enterprise solution to water leak detection throughout the entire water distribution system. it is the first economical and logistically sound approach to solving the problem of water loss between the treatment plant and the consumer, permanently reducing the production of non-revenue water.

mlog water leak sound detection sensor installed on service pipe next to the water meterInstallation

MLOG loggers are maintenance free - rugged, waterproof, and battery powered. They are installed either indoors or outdoors on a service pipe next to the water meter.




Data Collection

MLOG loggers record sound data from the distribution system for four hours every night. The recorded data is then transmitted to the utility in one of two ways:
Via the utility's existing AMR system or
Via radio transmission from the MLOG logger to a handheld MLOG Controller.


How Does It Work?

Step 1: An MLOG logger is installed on every 10th water service.


Step 2: AMR systems or utility workers with MLOG Controllers gather data from the MLOG Loggers. Data is then downloaded to a PC where the MLOG Analysis Software is installed.


Step 3: MLOG software analyzes the data and computes a Leak Index for each MLOG Logger and assigns a leak status as follows:

water leak detection analysis results presented by red sign near the water leak noise sound detection logger position corresponds to probable water leak nearby and this information must be urgently used by water utilities managers

Probable Leak
yellow sign near the water leak detection sensor position corresponds the low level and possible evolving water leaks within the finite period of time

Possible Leak
one green flash

No Leak Likely

Step 4: MLOG software provides a variety of tools including, color mapping, electronic and printed reports, and data management to direct the investigation and pinpointing of all leaks discovered.


MLOG Color Map™
mlog software prepared map for evaluation of leak

The MLOG Color Map shows leakage at a glance, overlaying leak index from MLOGs over the area of the water distribution system shown on the map to the right. The color image indicates areas of high probability of the presence of leakage (red) through low possibility of leakage (green).


MLOG Sound History

MLOG automatically detects changes in the level and frequency of pipe sounds from night to night. The sound pattern during the nighttime hours

is also analyzed every night. This specialized information about leakage activity contributes to the leak index at each MLOG location in the water distribution system. The screen below shows the sound history of a break in on a 2" main and its eventual repair.

MLOG Data Manager Software

MLOG Data Manager software displays and organizes all MLOG data from one or more distribution systems. This powerful software tool allows sorting, searching and ranking of all MLOG loggers by any of the following parameters:

  • Leak status/index
  • Map location; address; zone
  • Meter ID number
  • Logger ID number
  • Date of Installation

mlog database, to search and manipulate, manage the loggers, sensors data and information



visit page with comparison of mlog - managing water loss using acoustic intelligent sensors and advanced wireless communications - and other water leak sound detection logger systems. each low-cost, battery-powered mlog water leak detection noise sound sensor is permanently installed on a water service pipe near the water meter. mlog sensors analyze and save vibration patterns from every location in the water distribution system, using advanced signal processing to characterize water leak sound patterns in the pipes. the water utility is alerted to the presence of undergound water pipeline leaks with the wireless transmission of mlog sensor data. with the amr approach to water leak detection data collection, information from thousands of mlog water leak detection sensors is brought to the water utility manager´s desktop every morning. the mlog water leak detection system leverages the investment in amr, often paying for itself within 2 years of a specified 15-year operating life and providing an unprecedented amount of information about the integrity of the water distribution system


visit page of mlog financial benefit analysis with free software download: evaluate the economic cost of lost water. it is simple to predict the amount and source of lost water in a utility system. service line leakage predominates, typically accounting for more than 70% of total water lost. water pipeline integrity failure costs include: production / treatment cost of water; wholesale or retail value of lost water; capital and interest expense invested in surplus water production facilities; intangible costs from depletion of water resources, barriers to development due to water scarcity, and corrosion damage to buried infrastructure. download mlog financial benefits analysis software free
