LEAK CORRELATOR OVERVIEW

The SubSurface LC-2500 Leak Noise Correlator is very lightweight and compact, yet it offers full capabilities for programming many different pipe materials and pipe diameters.  View data on suspect leaks in the field or download the data to PC for further analysis.  Ruggedly built and weather resistant with an industry best, a 5 year - "NO BULL" warranty.  Pollardwater.com trains and supports you through the process - making sure those who use the machine are properly trained and ready to use the LC-2500.

Great Sensors, powerful radios and fast processing of sounds make the LC-2500 truly the best performing correlator for the money.  It all starts at the sensors - high sensitivity, small diameter sensors that work for metal and A/C water mains and optional low frequency red sensors for PVC pipe or plastic service mains.  The sound then goes from the sensors to powerful pre amp/transmitters with radios that go over hills and around buildings (500 milliWatts output sends signals up to 3,500 feet in each direction) to a powerful main processor unit that displays the correlation picture.

How it Works
The LC-2500 correlates the sounds found between two sensors that you place either directly on the pipe or on valves, hydrants, or anything else touching the pipe.  After inputting the type of pipe and the distance between the sensors, the LC-2500 listens and correlates the sound it hears.  If there is a leak, the sensors will pick up the noise created by the leak and send the data from both sensors back to the main processing unit where it will process thousands of data points into a graph showing the correlation or that data.  A spike on the graph (which might be created by the "hissing" of a leak) would be a good indicator of a suspect leak.

The Main Processor Unit and the Pre-Amps/Transmitters can operate in rain storms, subzero temperatures, and direct sunlight for hours.  The new LC-2500 sensors are very small in diameter and totally submersible - great for correlations using valves.  Runs all day on standard or rechargeable batteries.

The LC-2500 comes standard with Black Sensors that are used for standard metal and AC pipe.  Optional Red Sensors are for "Low Frequency" applications on PVC pipe, poly services or very large mains.

Basic Systems start at $19,950 for iron pipe sensors and $22,900 when you add in the plastic sensors.  For PC 's we offer the latest and best portable from Dell or HP - preconfigured and ready to use.  Please call customer service at 800-437-1146 (U.S.), or 516-746-0842 (All others), or request a quote for ordering.

In PIPE DATA INPUT, choose the pipe material, diameter, and length for every section of pipe between the two sensors.  Up to six pipe sections can be entered (always in order from the "Blue" sensor to the "Red" Sensor)

In FFT ANALYSIS, the user can examine the sound signals form both sensors from 0 to 5000 Hz.  The FFT function can automatically select the high and low filters if AUTO is chosen in FILTER SETUP.

In CORRELATION, the correlation "picture" indicates whether the leak sounds are clearly heard at both sensors.  The distance to the leak and the filter settings are displayed.
