Touch the Future with New MicroCorr Touch Correlator from HWM

The MicroCorr Touch from HWM is the world’s first standalone water leak noise correlator to feature a high visibility colour touchscreen, and it now features the unique Automated Filtering Intelligence System (AFIS) software to make accurate leak pinpointing quicker, easier and more accurate than ever.

New MicoCorr Touch Touchscreen Leak Noise Correlator from HWM uses AFIS to automatically optimise pipe parameter filter settings

Like most traditional correlators, the MicroCorr Touch provides default filter settings for a wide range of different pipe materials and sizes. However, due to the number of unknown variables that can change the frequency of leak noise, default filter settings will never be optimised for every leak situation. Experienced users can manually change the filter settings to find the leak, but this is often a time consuming process involving multiple correlations. Even then it can be ‘hit or miss’ to successfully locate the leak. With AFIS, the MicroCorr Touch effectively builds an expert user into the unit.

AFIS works by automatically applying multiple filter settings to determine the best possible correlation result every time. The system runs 55 different filter combinations on the correlation data, checking the quality of the result and optimising the filter settings as required, until the clearest and most accurate result can be presented. Working on live or pre-recorded data, tests have shown AFIS to significantly improve leak pinpointing on almost any pipe – effectively making manual filter setting a thing of the past.

In addition to this advanced software, HWM has incorporated the latest technological developments into the MicroCorr Touch’s hardware: best-in-class sensors, the VGA touchscreen, and an innovative carrying case that can charge the components from a mains or vehicle connection.

Specially developed by HWM for the new correlator, the new accelerometer sensors offer unparalleled sensitivity in the marketplace. In a recent project in Shandong, China, the local water company had visibly identified a leak presence, but correlators from three different companies were unable to even detect a leak signal – let alone pinpoint where it was on the pipe. When the MicroCorr Touch was deployed it immediately identified the leak and then determined its position to within 0.1m, confirmed by ground microphone and subsequent excavation.

The full colour touchscreen makes entering data incredibly easy, with an intuitive menu system quickly guiding operators step-by-step through the correlation process. By maximising the screen space without the need for button controls, viewing results and analysing the data is also easier and clearer than on traditional units. A high contrast mode for increased clarity in bright sunlight has also been built in, and the on-screen controls designed and tested for use with gloves, ensuring that the MicroCorr Touch retains its usability and functionality in all weather conditions.

The compact, purpose-designed charging case not only carries and protects all components, but also enables the base station and outstations to be charged from the mains or a vehicle via a single power lead. The charging status of each component is displayed on a panel inside the case, and units can be stowed with the sensors still connected. This means that a leak finding team can simply stow the kit safely in the case between jobs for it to be charged and ready for immediate deployment upon arrival.

MicroCorr Touch has been designed from the ground up by experts in both the technology and its application in the field. The result is a correlator that combines cutting edge design and highly innovative functionality to deliver outstanding results with the minimum amount of effort required from the operator.

SMART Log Helping Fight Leaks for Yorkshire Water

A major project to fight leakage by Yorkshire Water is using HWM’s Radio-Tech SMART Log wireless datalogging automatic meter reader (AMR) to significantly reduce the time and cost taken to find and fix leaks in the network. The SMART Logs are being installed by Vernon Morris & Co. Ltd. along with its Incertameter ‘bolt-on’ in-line flow meter, enabling Yorkshire Water to split 250 of its existing DMAs* in half for more efficient water management – without the need for constructing any new, expensive metered bypasses. The initial phase includes 350 installations, with more planned to follow as the project rolls out across the network.

Dividing a water mains network into DMAs is current water loss prevention best practice. It allows water companies to examine their network in small pieces, narrowing down areas where water is being lost so that leakage teams can then pinpoint the location within that DMA. Obviously, smaller DMAs result in more detailed initial information, and proportionally less time taken to identify the exact position of the leak; in these cases time equals not only money but also water, personnel and the chances of a severe service disruption.

SMART Log and Incertameter allow for the easy and very cost-effective creation of more and smaller DMAs, and very rapid collection of data from them. SMART Log’s wireless technology means that data collection teams no longer need access to the meter itself, but instead can download the data via a secure wireless link from up to 100 meters away – even from a moving vehicle. This drastically reduces the time taken for data gathering, which, in addition to the use of smaller DMAs, results in impressive savings.

In a series of blind pilot trials conducted last year to compare the before and after effects of the project, results indicated an average saving per leak of roughly 60 hours of detection time and over £1500, even without factoring in the initial saving of £5000+ per sub-metering point created. Leakage inspectors can expect to cover a DMA approximately five times faster than before, and prioritise their leak repair activities much more effectively according to the severity of a leak and its impact on the water supply.

Advanced technology not only enables this level of functional efficiency, but has resulted in an impressive battery life for the systems. Batteries last for 5 years with a 5 minute sample rate, meaning that the time and cost savings first made at the installation continue on for half a decade. The SMART Log technology has already seen extended use in Scotland and England over the last few years, both in conjunction with the Incertameter and as a standalone AMR or commercial datalogger, and has consistently proved itself a valuable tool in improving a project’s operational functionality and underlying efficiency.

New Braunfels Utilities Cuts Water Loss by 50 Percent with FCS Leak Detection

Equipment helped department exceed water loss reduction goal

Milford, OH (December 14, 2011) – Texas-based New Braunfels Utilities (NBU) used leak detection equipment from Fluid Conservation Systems (FCS) to build an efficient maintenance program for its distribution network while drastically reducing water loss. The equipment allows NBU to conduct scheduled repairs on its pipelines instead of dealing with leaks on an emergency basis.

NBU workers use an FCS TriCorr Touch correlator to locate leaks and conduct scheduled maintenance.

NBU workers use an FCS TriCorr Touch correlator to locate leaks and conduct scheduled maintenance.

The NBU leak detection and valve maintenance program was established in 2009 to reduce water loss and increase system and valve reliability for NBU’s 456 miles of pipeline and 24,000 customer connections. At the end of the first year of the program, NBU calculated its average water loss at 2,000 gallons/ mile/ day.

Recognizing the need for improvement, NBU purchased FCS leak detection equipment including Xmic ground microphones, a SoundSens “i” correlating noise logger, a TriCorr Touch correlator and Permalog acoustic leak noise data loggers. The team began using the equipment to perform preventive maintenance on 750 valves per year and proactively scan the city for non-surfacing leaks. Two years later, NBU estimates its average water loss at 961 gallons/ mile/ day, less than half the loss rate during the program’s first year.

“Everyone knows that water is a precious resource and its preservation requires a ton of attention,” said NBU Operations and Maintenance Division Manager, Trino Pedraza. “We tested many products in the field and found FCS to have the highest level of reliability.”

FCS Permalog data loggers attach magnetically to pipelines and use advanced algorithms to discern the acoustic signature of leaks from background noise. SoundSens “i” and TriCorr correlators analyze data from acoustic sensors to approximate a leak’s location. The FCS Xmic electronic ground microphone amplifies noise generated by water escaping from buried supply lines under pressure, allowing users to pinpoint a leak’s location.

Hong Kong Water Network Protected by PermaNet SMS Leak Detector Network

Hong Kong was the first city in Asia to take advantage of the advanced leak detection capabilities of the Permalog noise loggers, with an initial deployment back in 1999. The loggers are placed on water pipes where they listen for the sound made by leaks, log the data and then transmit it for further analysis. This enables water companies to identify leak areas quickly and efficiently; saving time, money and water by enabling a rapid, accurately-targeted response to repair the issue.

In Hong Kong, the Water Supplies Department (WSD) is in charge of maintaining the 7800km of underground water pipes in the city, and has a 15-year rehabilitation program costing billions of HK dollars to repair, upgrade and modernise the network. Their target is to reduce burst incidents from 2500/year in 2010 to 1000/year by 2015, and to decrease the leakage rate from 25% to 15%. Out of the 1100 cross-road pipes, around half are very old, and at increased risk of damage and disrepair.

When a pipe in the busy Wanchai district burst recently, the Hong Kong government identified a further 600 sites around the city where very old pipes run under busy streets, and deployed a new batch of Permalog+ noise loggers to watch for, identify and locate any leaks in these areas. 

Permalog technology is made and developed in the United Kingdom by Halma Water Management (HWM-Water Ltd), and the company’s distributor in Hong Kong is Allied Power Technology Ltd. Allied Power has supplied over 800 sets of Permalog+ units with SMS repeaters to the region, and also has a contract with the local government to analyse the data gathered from the system.

When deployed with SMS repeaters, the Permalog+ devices can function together as a nodal network, with all data being automatically transmitted back to a ‘home station’ – in this case Allied Power’s offices. Every morning, the company receives the leakage data for each of the install sites, and makes recommendations to the WSD based on this information.

Davis Li, Managing Director, said: “We manage a huge amount of data every day, which has to be organised and presented clearly. Because the noise loggers are on busy roads for this project, there is quite a lot of interference from road noise, which can complicate our job. The main challenge of this monitoring work is to localise a leak when a correlation is simply not possible. In these situations, we usually use the Permalogs’ Aqualog function to differentiate interference and help identify the leak location.”

When in Aqualog mode, a Permalog+ logger will measure and log acoustic data at preset intervals over an extended period of time, typically at night to minimise the traffic noise. This data can then be presented graphically so trends, anomalies and incidents can be clearly identified. This effectively displays whether or not the noise is caused by a leak, since any leak noise will be consistent.

The combination of the automated leakage data transmission for general leakage alerts, and in-depth on-site analysis with Aqualog, means that leaks can be quickly identified and problems repaired before they cause major disruption or damage to Hong Kong and its residents.

FCS Helps Town of Mooresville, N.C. Improve Response to Water Leaks

Equipment finds leaks before digging to minimize repair costs and road closures

Milford, OH (June 27, 2011) – Water leak detection specialist Fluid Conservation Systems (FCS) helped the town of Mooresville N.C. save money and resources while keeping in compliance with state regulations.  With FCS leak detection equipment, Mooresville can now identify and repair leaks in its water distribution network as they occur.

The Mooresville Public Services Department installed FCS equipment allowing leaks to be found and repaired as they happen.

The Mooresville Public Services Department installed FCS equipment allowing leaks to be found and repaired as they happen.

Mooresville is a town of 33,000 people that provides an average daily flow of 3.24 million gallons of water to 13,000 homes and businesses.  In the summer of 2008, officials at Mooresville Public Services Department were experiencing a 10% non-metered water rate in their 240 miles of water mains.  Underground water leaks were causing damage to roadways, and the extensive digging required to find and repair these leaks was expensive and caused heavy traffic congestion.  With the passage of North Carolina House Bill 2499 requiring public water services to develop and implement water conservation measures, as well as new industry moving into town that would drastically increase water usage, officials knew it was time to upgrade their water distribution network maintenance program.

After evaluating competing products, Mooresville officials decided that acoustic leak detection equipment from FCS most closely met with their operational and budget requirements.  “The FCS equipment was compatible with our record keeping system and simple enough so that the guys in the field could use it and feel confident that they were collecting accurate results,” said Mooresville Public Services Director, John Vest.

Vest contacted local distributor Carolina Meter & Supply (Hampstead, N.C.) and purchased Permalog leak noise loggers, L-Mic and X-Mic ground microphones, an AC Digital leak noise correlator, and a Patroller II system to allow leak data to be collected from a moving patrol vehicle.  The equipment was fully installed and in use by the fall of 2009.

In April of 2010, Mooresville Public Services staff had located and repaired 24 leaks, saving an estimated total of $80,000 annually.  Workers were pinpointing leaks accurately, allowing preventative maintenance work to be scheduled with advance public notification to avoid traffic congestion.  “The FCS equipment has really enhanced our planning capabilities.  We’re finding leaks before they become a problem,” said Field Operations Supervisor, WD Bumgarner.
