Ecosense is available in three versions: internal, external (reading both temperature and humidity), and surface (reading only temperature conducted through a wall). The sensor “chirps” every five minutes, transmitting its data to Radio-Tech’s RT:Wi5 data hub (or a modbus receiver); the information collected is then sent directly to the relevant server.

Aimed at the construction industry and energy consortiums, Ecosense was originally designed for the Energy Saving Trust in the United Kingdom. The product supplied to that body correlates measurements of internal and external temperature and humidity, along with wall surface temperature, to evaluate the insulation of new housing.

Since Ecosense’s transmitter is radio-based and needs no connection to mains electric power, the sensor can be installed very easily. The unit is powered by a lithium battery that lasts up to three years.

New G-6 Gonio Lens from Volk Offers True 360 Degrees

G-6 Gonio lens reduces eye examination time by 25 percent or more

Volk Optical has developed a new Gonio lens with the most comprehensive sweeping views of the anterior segment of the eye. The G-6 Gonio’s six closely aligned mirrors provide a true 360° view during glaucoma screening, without any lens adjustment required.

The lens’ six mirrors are equally angled at 63°, eliminating gaps for visualisation of the entire anterior segment at 1.0x magnification.  During examination, two of the mirrors are aligned in the superior and inferior regions, while the remaining four mirrors provide a continuous view through the nasal and temporal regions.  Practitioners can quickly scan across mirrors, without the confusion of tracking where one view ends and the next begins that can come from rotating the lens. This fast scanning and less need to manoeuvre the slit lamp can reduce examination time by 25 percent or more.

The G-6’s taller, tapered profile is easier to hold within the orbit and lessens the chance that a patient can squeeze it off the eye. The “nf” (no flange/no fluid) design of this lens facilitates use without viscous interface solutions.  For handling flexibility, the G-6 comes with a ring or a versatile 2-in-1 handle that can easily be adjusted to create a straight or 45° angled grip.

New Range of Portable Arsenic Test Kits from Palintest

The new DigiPAsS and VisuPAsS systems from Palintest Ltd offer accurate, laboratory-standard Arsenic testing in a portable field kit format. Both options use the well-established Gutzeit method to detect Arsenic levels in drinking water, up to and well beyond the WHO recommended maximum of 10 µg/l.

The method first converts all Arsenic in a sample to Arsine gas, which is then completely captured by the unique three-stage filter. This ensures excellent accuracy, with no toxic gas release, over the 20 minute reaction time. The result can be assessed either visually against a colour chart (100 – 500 µg/l) or analyzed by the dedicated DigiPAsS instrument with accuracy and precision across the 2-100 µg/l range comparable to AAS. The simplicity of the VisuPAsS system makes it especially suitable for more challenging environments, or where costs must be kept to a minimum.

Arsenic is a naturally occurring contaminant of drinking water in several areas of the world, and even at very low concentrations it causes a variety of serious conditions known collectively as arsenicosis. Symptoms may not even appear until after many accumulated years of drinking contaminated water. The need for accurate testing at low concentrations is therefore vital to continued water safety, and these new Arsenic test kits from Palintest Ltd. offer laboratory quality analysis for on the spot verification.

Memco’s Elite safety system features two independent detection systems. The first is a light curtain of infra-red beams criss-crossing the elevator car’s doors; the second is a 3D proximity detection system in the landing zone. Any person or large object breaking the light curtain or detected within the 3D zone triggers a system which automatically reopens the elevator doors.

The combined system consists of a transmitter detector (TX) and receiver detector (RX) mounted on the car doors. Each housed in a robust profile only 9.8mm wide, they automatically sense door separation and adjust themselves for optimum performance. In many installations a separate controller is unnecessary and the detectors can be connected directly to the door controller or elevator operator.

The Elite features the latest software as standard, including power reduction and timeout features, and can be fitted to virtually any new or existing elevators. This versatility makes it one of the most competitive and easy to use elevator safety systems on the market (more information can be found here: http://www.memco.co.uk/en/elite/674.html).

Indira Gandhi International Airport is the busiest airport in South Asia by traffic movements and passenger volume. It serves as the primary civilian aviation hub for the region and in 2007 it handled 23 million passengers, with a planned expansion programme increasing its capacity to handle 100 million passengers by 2030.

The new Terminal 3 building, expected to cost US$ 2.6 billion, will have the capacity to handle an additional 33 million passengers annually by the start of the 2010 Commonwealth Games in October. On completion it will be the third largest terminal in the world, after Dubai International Airport’s Terminal 3 and Beijing International Airport’s Terminal 3.

It will be a two-tier building, the bottom floor being the arrivals area and the top being a departures area. It will have 168 check-in counters, 74 aerobridges, 72 immigration counters and 15 X-ray screening areas, along with duty-free shops and other features.

Halma Water Management’s (HWM’s) ‘Lift and Shift’ Leak Monitoring Reduces Water Loss and Costs for Veolia Water

Veolia Water, the major water and wastewater management company, has been making use of recent developments in water leak detection technology to effectively manage water networks at an increased efficiency and lower cost. Halma Water Management’s (HWM’s) Permalog+ noise loggers have been employed by the company in a ‘lift and shift’ method to quickly, easily and accurately find and repair leaks.

Permalog+ Technology
Permalog+ noise loggers are small devices deployed at points around the water network, where they monitor the noise levels on the pipes themselves. Changes and distinctive patterns in sound indicate the presence of leaks, often including ones that would otherwise go completely undetected. Mounted directly onto the pipes by a strong magnet, and battery-powered, the Permalog+ units can continuously monitor the section of piping around them for tell-tale signs of a leak. Once found, various telemetry and communication methods are available to alert leak detection operatives either immediately or at a specified time.

In a typical usage scenario, the data will either be collected or sent back to a central database, where each logger’s location is displayed on a map with either a green flag for ‘all clear’ or a red flag to indicate a leak. Each logger’s serial number, noise level and noise spread (the leak ‘signature’) is displayed alongside them on the map.

‘Lift and Shift’
Veolia Water has nine Noise Logger Technicians to carry out ‘lift and shift’ operations, with an average of over 80 individual Permalog+ units deployed and retrieved by each technician every day. The ‘lift and shift’ temporary installation method allows the use of a smaller number of units to cover a large area, effectively ‘auditing’ the network for leaks. As an alternative to a permanent installation, where the loggers would sit waiting and monitoring for new leaks in order to address them immediately, ‘lift and shift’ deployment actively searches for leaks throughout the network in a ‘sweeping’ pattern.

Leakage Teams will deploy loggers throughout the next targeted area (typically divided by DMA*), where they will remain overnight. The following day, the loggers are collected by the team, with a centralised record being made of where there are leaks and where the system is clear. These loggers can then be deployed to a new area, and so a rolling, sweeping search for leaks quickly progresses throughout the network.

In contrast to a ‘permanent’ deployment pattern, Permalog+s for use in a ‘lift and shift’ operation will be either pre-programmed at the factory or by the user with specially designed software to only transmit their recorded data when an operative swipes them with a magnet. There is no radio interference from other loggers nearby (stored in the car, for example), and the data is kept both secure and easily compartmentalised. This is obviously useful when the same loggers will eventually be deployed in many different locations – the fundamental point of the ‘lift and shift’ method.

Ease of Use
The Permalog+ units and system incorporate several recent technological innovations by HWM to make them more efficient and easier to use than ever before. The loggers can be pre-programmed, and can automatically record each deployed unit’s serial number and location by GPS tracking. This means that deployment is very quick, and there is no longer a danger of misplacing loggers – or the maps of where they are – which of course means that retrieval is easy too.

The new Permalog+ version can also utilise the extended logging functionality of Aqualog. This records noise levels at set intervals over a longer time period of up to 29 days. This allows easy trending analysis and graphical representation of the data, providing for more detailed leak analysis and definite confirmation. User-configured or preset alarm threshold settings can be applied for different pipe types and diameters.

Results
Veolia Water has had excellent results from this operation, finding leaks with great speed and ease, leading to reduced costs from resources. The new GPS mapping technology tracks and makes visible the effort being applied by the one-man teams, and has resulted in a higher deployment rate than previously seen. It also gave the company an audit trail of loggers, ensuring accountability and precise location tracking.

With over 80 loggers per technician per day being deployed and collected, the speed of the activity means that detection time can be reduced when compared to other, more traditional leak-finding technologies and methods. A recent Veolia project that involved targeting 15 DMAs, covering some 28,000 properties, took only 32 days to sweep, and 96 leaks were detected. Because time lost is water lost, the speed of the search and therefore the swiftness of the response is key to minimising waste and reducing NRW** levels. Certainly, given the right application, noise loggers in the ‘Lift and Shift’ mode provide an excellent return on the investments of both time and funds. The fact that the Permalog+ system is very accurate in terms of both location and detection, as well as sensitive enough to find even ‘hidden’ leaks, makes it a powerful and effective tool in the ever more important fight against water loss.
