HWM Launches New Touchscreen Water Leakage Correlator with Class-Leading Sensor

Posted: Monday 11th October 2010

Halma Water Management (HWM) has developed a new water leak correlator that features a class-leading sensor, a large full-colour touch screen, and integrated noise filtering, analysis and management software.

The company, which incorporates Palmer Environmental Ltd., developed the first correlator over thirty years ago, and has been at the forefront of leak detection design and manufacture ever since. With significant improvements to existing components and the addition of brand new features, HWM believes the new MicroCorr Touch (TriCorr Touch in the USA) represents a real breakthrough in leak detection technology. The unit is operated by touchscreen, making it much easier to input data and maximising the visible screen area to display results more clearly than has ever been possible before.

Leak correlation is used to find the exact location of a leak on a pipe. Highly-sensitive acoustic sensors are placed at intervals on the pipe, and listen to the sound made by the leak. The data is transmitted wirelessly to a handheld ‘base unit’, which processes the information to identify the leak sound, and then applies mathematical algorithms to to pinpoint the leak position.

The Touch features a newly-developed sensor designed to be at least twice as sensitive as anything else available on the market today. This enables it to perform well even in traditionally difficult conditions, such as on plastic and large diameter pipes. It is also the first standalone correlator to feature a high visibility full colour VGA touch screen to greatly improve data entry and the quality of data presentation. The intuitive user interface eases and simplifies leak-finding without compromising on functionality or precision, and enables the unit to be operated with the minimum number of key presses. The large screen, with Tuffscreen anti-glare screen protection, clearly displays correlation results and supportive information even in bright sunshine, effectively combining outstanding performance with excellent ease of use.

The system is equipped with an innovative tri-filter correlation option which can simultaneously perform three correlations at different filter settings. This is particularly useful when the pipe material is uncertain. When the best filter is seen, the correlation switches to focus on this. The outstation is compact with high quality long range radio transmission; it also features a magnet to secure onto metallic street furniture. The purpose designed robust case not only carries and protects all components but charges them via mains or vehicle supply. The charge level for all items can be shown at the touch of a button.

Using the company’s extensive experience of correlator technology, HWM believes that it has created an easy to use system that delivers the best all round performance available today at a highly competitive price.
