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.

Leak noise amplification system identifies and locates leaks

Milford, OH (September 10, 2010) – Leaking pipes in a water distribution network produce a distinct noise that travels along the pipe, through the water and sometimes to the surface.  To detect and locate this noise, Fluid Conservation Systems (FCS) offers the S30 Surveyor leak noise amplification system.

The S30 Surveyor leak noise amplification system from FCS.

By placing the S30’s sensor in contact with any access point (valve, hydrant, etc.) in the distribution system, sound from the pipeline is transmitted through the S30’s aviator-quality headphones allowing the operator to listen for leak noise.  The device’s analog meter measures the noise intensity in the pipe and, by listening at several points in a given area, the user can determine the general location of a leak.  The S30 is also supplied with a surface sounding plate, which attaches to the ground sensor and allows operators to pinpoint the exact location of the leak.

General Environmental Services Ltd (GES Water and GES Technology) has signed a distribution agreement with Radio-Tech to provide its clients with aquavision, Radio-Tech’s wireless legionella* management system.

GES supplies customers with water treatment and hygiene programmes and legionella monitoring forms a core part of its business. Kevin Bloodworth, Director of GES Technology is responsible for driving innovation and looked at several methods of improving legionella control. He commented:

“We found that Radio-Tech’s product was by far the best product on the market. aquavision goes above and beyond the minimum standard of legionella monitoring set out in HSE’s ACoP L8 guidelines. Clients get a better overview of the system and it enables them to identify problems that they wouldn’t otherwise be able to see, so it’s a great investigative tool.”

aquavision works by wirelessly monitoring water temperatures at multiple sites from any internet enabled location. It is a fully automated system that has been developed to assist water treatment companies, facility management and property management companies to comply with current guidelines and legislation.

Kevin noted that Radio-Tech’s product enabled GES to give clients an all-round better service: “With aquavision, the process is automated so clients don’t have to remember to manually check temperatures every month, or make sure the contractor has been in to do it. It also helps us cut down on the number of vans we send out thereby improving our costs and environmental footprint”, Kevin said, adding, “We can also offer aquavision to clients on a lease basis which provides a much-improved and cost-effective solution to customers.”

Using aquavision to wirelessly monitor water temperatures is less invasive than the traditional method of manually checking and automatically flushing outlets on each floor of a building.

Kevin continued: “aquavision has other advantages; sometimes there are security or privacy issues at certain properties, or the need to be discreet. For example, care homes often don’t want strangers intruding in resident’s personal living space every month, which can be very disruptive. aquavision eliminates this issue by remotely and wirelessly monitoring water temperatures regularly without the need to enter private property.”

Craig Anderson, Sales Manager at Radio-Tech commented on the new partnership deal with GES: “Their wealth of knowledge and experience in the water industry combined with our technical and design abilities make this an ideal partnership.”

*Legionella – L.pneumophila, a bacterium that causes Legionnaires’ disease.
