Leading water management and remote datalogging product developer and manufacturer HWM-Water Ltd. has launched its new website, now including the wireless energy and environmental monitoring ranges of Radio-Tech in addition to the well-established HWM brands of Palmer leak detectors and Radcom dataloggers. Radio-Tech was recently merged into HWM, bringing the benefits of shared expertise and technology to all areas of the business. The web address is the same as before: www.hwm-water.com.

New website for water management and leak detection company HWM includes Radio-Tech energy and environmental monitoring ranges

The new website makes it easier to find out information about the company and its extensive range of products, split into the three sub-brand product groups. Datasheets, user manuals, training information and even software/firmware updates are now available on the site, with customers also able to log in to access even more useful information.

Palmer Environmental is one of the world’s most recognised names for water leak finding and pinpointing equipment, including Permalog noise loggers, ground mics, digital correlators, flow measurement and pressure control. These are used around the world to find, reduce and fix leaks in water mains networks to save time, money and the precious resource of fresh drinking water.

Radcom Technologies offers, amongst others, the MultiLog LX data logger with remote telemetry options, the SonicSens ultrasonic level monitor, and the Senator+ satellite transmission system for automated data collection from areas even without mains power or mobile phone signal coverage – such as environmental monitoring in the Scottish Highlands.

The latest addition, Radio-Tech, brings a market-leading range of RF-based wireless monitoring and data collection devices that are predominantly used in and energy management, automatic meter reading (AMR) for utility companies and legionella control.

Following the merger of Radio-Tech with HWM last year, the highly respected and popular Economise range of wireless energy management equipment has been further strengthened with the integration of HWM’s market leading range of SMS and GPRS Data Loggers. The company’s offering to the energy management market is well suited to all types of project, providing new and continuing customers with a ‘one-stop-shop’ for their remote monitoring requirements.

Radio-Tech Merger with HWM brings new wireless energy and environmental monitoring products for all sized premises

Radio-Tech is already established as the Technology Partner of Choice for many of the UK and Europe’s leading data collection and carbon management service providers. This new enhancement to the Economise range will now enable Radio-Tech and its partners to offer an innovative, cost-effective and robust battery-powered data logging option for single point monitoring applications that compliments the existing fixed-network systems.

Radio-Tech’s RF based products are fully approved in the UK and Europe and are available on 434MHz, 869MHz, 153MHz (UK Only) and 169MHz ERMES band for many European countries.

Rob Fish, Managing Director of HWM, said: “It’s great to have the Radio-Tech operation here now, and we think we can really build on the existing technology, products and markets they’ve developed. Our expertise in the production and design of long-lasting, reliable and precise monitoring and data management systems is already helping us to develop the full potential of wireless environmental and energy monitoring.”

Since the merger, Gavin Farrand and Matt Dillane have joined the Radio-Tech team as the account managers for UK North and UK South respectively, and will be keen to introduce customers new and old to the finer points and latest developments in the Economise and Observe product ranges. The company also welcomes Matthew Hoblyn as a Technical Support Engineer, and Phil Tomlinson who will be developing Radio-Tech’s Export business.

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.

SMART Log wireless dataloggers from HWM Radio-Tech help Yorkshire Water fight water leakage

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.

SMART Log wireless datalogging automatic meter reader (AMR) reduces time and cost of finding and fixing water leaks

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.
