HWM Palmer launches its new Permalog+ noise logging system for water leak detection, building on the reputation and features of the established Permalog and Aqualog series with enhanced functionality, usability and capability.

The ‘drive-by’ version uses a new PDA-based Bluetooth Patroller unit with integral Aqualog noiselogging mode, customisable programming and radio connectivity.  The tailored design and expanded feature set offer improved surveying speed and faster data collection for increased drive-by speed.  Full Aqualog graphical noise logging for quick, in-depth analysis is also available, and historical data can be downloaded to provide comparisons over time.

The Permalog+ can also be used to form a permanent, fixed network, by combining it with a PermaNet radio or SMS repeater to send telemetry data at fixed intervals to a remote receiver – such as an office desktop PC.  The PermaNet setup can be also be configured to automatically send a ‘leak’ alert, allowing for immediate action to be taken.  With a complete network of devices, a powerful system can be created to supply up-to-date flow data and effective leakage detection, location and information.

The arrival of summer marks many things each year – the return of cricket and tennis to our shores, the frenzied covering up of every patch of green ground by people lying on it, and ‘unexpected’ rain falling on it all.  Glastonbury festival is another mainstay of the British summer, and whether drowning in mud or basking in sunshine, it involves a massive temporary migration (~180 000 people this year) to the village of Pilton, where masses of music fans decamp and lay siege to the soundstages.

Despite rumours and folklore to the contrary, these festival-goers do in fact both wash and occasionally drink water rather than beer or cider, and the strain put upon the local water network is measurable.  Proving this, Bristol Water were on hand to measure and closely monitor the flow and pressure status in Pilton village and on the festival site itself.

Frank Van Der Kleij of Bristol Water said this: “In the past, there had been pressure problems when large amounts of water were used at the festival, and the datalogger information is now used to anticipate any supply problems”.  There is continuous monitoring of the water supply network at a district meter area already through Radcom Centurion PSTN dataloggers, and for the duration of the event three additional Radcom GSM Multilogs were deployed.  They were set up to regularly transmit vital data to an on-site office, where a team of network inspectors used the telemetry to ensure that the water supply to the local area was not adversely affected by the demands of the festival. 

The weather was also apparently concerned about potential shortages, and with over-enthusiasm saw fit to supply the event with a surplus of water, delivered directly from above.
