Water Networks Leak Detection Instruments & Systems
The Pro-series correlators represents a breakthrough in leak detection technology. It features improvements throughout the leak noise processing path to provide improved performance; especially in the most difficult leak detection situations. This enables it to give the best performance in traditionally difficult conditions, such as on plastic and large diameter pipes.
Easy To Use
Pro-series features a high visibility full colour VGA touch screen to greatly improve data entry and the quality of graphical presentation. The intuitive user interface enables the unit to be operated with minimal key presses and the helpful step by step menu system easily guides the user through the correlation process.
High Quality Performance
The large screen clearly displays correlation results and supportive information, and the innovative high contrast mode enables good visibility even in bright sunshine.
The unique Automated Filtering Intelligence System (AFIS) automatically runs up to 55 different filter combinations on each correlation, checking the quality of the result and optimizing the filters until the best result is obtained. AFIS works with both live and pre-recorded correlation data and makes manual filter setting a thing of the past by effectively building an “expert user” into the unit.
The outstation is compact with an upgraded high quality, long range radio transmission. It also features a magnet to secure onto metallic surfaces.
Robust for Long-term Use
The specially designed robust case not only carries and protects all components, it also allows the base station and outstations to be charged from a single power lead and displays charging status. Units can be stowed with sensors still connected for faster deployment in the field.
Using the extensive experience of correlator design and manufacture, an easy to use system has been created that delivers the best all round performance at a highly competitive price.

P-series+ Correlation Logging System
The P-series+ Correlation Logging System builds on the proven reputation of the previous leak noise logger models but brings new advanced features:
Flexible deployment – permanent, semi-permanent, or ‘lift & shift’
Remote listening mode
Auto download of 1 month history
P-series Correlator+ enables water suppliers to quickly and efficiently locate leaks in the water network. Loggers are deployed in areas of the distribution system to provide continuous monitoring of leakage. Easily installed on pipe fittings, they are retained in place by a strong magnet. As soon as a potential leak is detected, the unit enters an alarm state and transmits a radio signal to indicate a "LEAK" condition.
When a leak is identified, the unit automatically records the noise for radio download correlation and sound file listening. Water suppliers can monitor 100% of their distribution system confidently and effectively, enabling leakage to be reduced quickly, and easily maintained at a low level.
The new logger features a small low cost USB radio receiver designed to be used with tablets or other compatible devices running the P-series Correlator+ software.
P-series Correlator+ software provides map based displays and all functionality for:
Multiple operating modes
‘Lift and Shift’
Noise data and history
Sound file listening
Lift and Shift Data Collection
The P-series Correlator+ “lift and shift” mode is designed for use in a rapid deployment mode allowing users to distribute loggers into the distribution systems, quickly identify potential areas of leakage and then re-deploy the loggers into another area.
Drive By Data Collection
P-series Correlator+ has an improved surveying speed enabling fast radio download of new data, including full noise logging graphics where further investigation is required. The drive by version features a new PDA based bluetooth collector to enable remote multiple logger programming and download.
Noise data and history – 28 days check
Sound file listening
DX-series Ground Microphone
DX-series is the latest generation ground microphone from Sigma Hellas. Building on the excellent reputation of the X-series, the DX-series features touch screen operation and a wealth of new innovative features.

CL - SERIES WATER LEAK DETECTORS
Water leak detection with the Professional CL Series is a non-destructive and efficient method for locating leaks in underground pipes and infrastructure. It helps minimise water wastage prevents costly water damage, and avoid excavation and disruption to the surrounding area by precisely pinpointing the leak's location. This technique is commonly used by professional plumbing and utility companies as well as municipal water departments to maintain water systems and minιmise water loss.
The CL Series acoustic leak detection devices are sensitive instruments designed for water leak detection by capturing and amplifying the sounds generated by water escaping from buried pressurised pipes, and used to identify and locate underground water leaks in water mains, as well as other water infrastructure.
The CL Series is the latest generation of high accuracy underground water leak detectors. The CL Series features touch screen operation and a wealth of new innovative features.
