Subsurface Instruments LC-5000 Leak Correlator Instruction Manual

LC-5000
Leak Noise Correlator

 LC-5000 Leak Correlator

Compact and Light-Weight.
The Main Processor Unit, weighing less than 5 lb., can easily be carried all day

The Main Processor Unit displays up to 6 Correlations on one screen.
User can easily drill into individual correlation from touch screen.
Ruggedly Built & Weather-Tight
The Main Processor Unit and the Transmitter Sensors can operate in rain storms, sub-zero temperatures and direct sun for hours.
Rechargeable Batteries
Runs all day on Lithium lon Batteries.
High Sensitivity Transmitting Sensors Standard
The new LC-5000 Transmitting Sensors are very sensitive, small in diameter, and totally submersible. 4 times the resolution of its predecessor the LC-2500.
Easy To Set Up & Run – 3 
Steps & You Are On Your Way
Input pipe materials, diameters, and lengths by simply selecting them in the program menus. Automatic functions can do the rest.

Easy To Set Up & Run

MAIN CORRELATION SCREEN, is the “home page” where every correlation begins. Icons at the bottom relay signal & battery strength. In PIPE DATA SCREEN , user enters Material, Diameter & Lengths from the easy touch screen menu.
In FILTER SCREEN, user can adjust High & Low-Pass Filter ranges & adjust Notch Filter.
In TRANSMITTER SENSOR SETTINGS, the user can program & send settings to all units or select individual units for Relay or Relay & Pre-Amp Mode.
In PRE-AMPLIFIER / TRANSMITTER MODE, user has options for programming as Transmitters, Relays, Transmitter / Relays or Logger Mode for overnight or Short Term Deployment.
MENU SCREEN, is where user selects various functions like Data processing, Logger data retrieval, Equipment seting as well as FFT & White noise features.  Powerful Transmitter with Radios That Go Over Hills and Around Buildings

Pre-amp / Transmitter
“hear” the leak sounds at pipe locations and transmit them to the main processor. aviation-grade stereo headphones are standard.
High sensitivity small diameter
LC-5000 Transmitter Sensors standard for all pipe materials.
Patented Submersible Sensors Deploying all 4 Transmitting Sensors allows for up to 6 correlations on Main Unit main screen. 4-1 Radio and Cable Modes
(1) Radio mode (2) Cable mode
Cable mode is used when radio communication cannot be established between the leak detector and the pre-amplifiers due to interference from buildings or other radio stations etc.
Normally, leak detection is done in radio mode as shown in (1) above. 4-2 Example of Detecting a Leak in a Pipe
This section explains how to perform leak detection for the pipe shown below.
In this example, it is assumed that the water leaks from a certain location in the pipe. The pre-amplifiers detect the leak noise and send the signals to the main unit. MODEL LC-5000
