18 WET NEWS february 2015 WHAT'S NEW! GPRS data transmission added to logger HWM has added GPrS data transmission to its pressure transient logging capability. The new GPrS Pressure Transient Logger triggers a capture window around a transient event and transmits this data, keeping costs down and prolonging battery life. The 'event window selection' feature allows operators to send transient alarm information and a selectable window of fast logged Medium submersible pump range launched Grundfos has announced the release of a new range of medium SP submersible pumps. The newly extended family offers four options – 7, 9, 11 and 14 – and will mean better coverage of duty points and higher efficiencies across flow ranges meaning lower running costs. a range of new features combine to deliver many new and improved benefits. These include data before and after the event. Network transient monitoring is now feasible via remote telemetry rather than manual site surveys. as transients are immediately identified, swift remedial action can be taken to avoid burst and infrastructure damage. The sampling rate on the logger's pressure transient channel extends to 100 times a second and operators can define sampling intervals and transient data capture trigger levels. The company said with the optional addition of flow channels, the unit is able to provide comprehensive transient and network monitoring. www.hwm-water.com Tel: 01633 489 479 Secondary validation added to leak detection Water and asset monitoring specialist HWM has added secondary validation to its PermaNet leak detection system. Once a leak is identified, the new PermaNet+ gives operators three secondary options to check for false positives prior to team deployment: remote correlation, remote retrieval of a detailed aqualog noise graphic or listening to an audio file transferred to the host PC. every component of the PermaNet+ system is installed in the chamber, removing the need for expensive and disruptive above-ground installations. With multiple secondary validation FlowCERT achieves Class 1 level pass Pulsar Process Measurement's flowCerT non-contacting ultrasonic open channel flow measurement systems have each achieved the highest Class 1 level during re-certification to the latest, more rigorous version of the MCerTs improved cable guards that mean better protection of the motor cable. The inclusion of an integral non-return valve minimises the risk of pump damage in cases of water hammering. With a modular construction this means easier assembly as well as a reduced need for component stocking. add to this the inbuilt assurance provided by their stainless steel construction, coupled with the fact that they come complete with sand-resistant bearings (150ppm) as standard plus the fact that the new range not only meets but in many instances exceeds the 2015 MeI (Minimum efficiency Index) 0.4 standard. www.grundfos.co.uk Tel: 01525 850 000 certification process. The flowCerT Lite and flowCerT with Duet are dedicated open channel flow monitors, both of which make use of Pulsar's DaTeM echo processing software to achieve rock-solid measurement. flowCerT Lightweight flood defence launched Ultrasonic flow sensors for metering Lite uses Pulsar's db3 transducer, with its high-frequency crystal array for high resolution in the measurement, and an external temperature sensor. Duet, designed specifically for flowCerT, is Pulsar's twin-transducer array that integrates the signals from the two separate sources to render the system almost completely impervious to any variation in the speed of sound within the air column within the channel. flowCerT with Duet was measured with a Combined Performance Characteristic of 0.044% error. www.pulsar-pm.com Tel: 01684 891371 Morgan advanced Materials now offers a comprehensive range of ultrasonic flow sensors for domestic and industrial utilities metering that can be specifically tailored for individual customers. Manufactured from a wide variety of materials including stainless steel, ceramic, thermoplastic or composite polymer, Morgan's ultrasonic sensors are designed specifically for customers' own flow tubes, including features such as injection moulded ceramic reflector blocks, which enhance flow characteristics. Morgan's ultrasonic flow sensors provide consistent readings across a temperature range of -10ºC to 120ºC. This enables users to take precise measurements across a range of diverse applications and environments; including the oil and gas industry, large industrial ultrasonic flow systems and fuel measurement technologies. Temperature stability is critical to heat meter manufacturers to ensure accurate measurement of domestic hot water consumption utilised in district heating. This crucial property ensures flexibility, consistency and dependability in applications operating from 50ºC to sub-zero climates. as well as their tolerance to extremes of temperature, Morgan's ultrasonic sensors are resistant to contamination from sediment and particles, ensuring uninterrupted and reliable operation. www.morganadvancedmaterials.com Tel: 01299 827000 IbS engineered Products has a new lightweight version of its glass flood defence system now available in the uK and Ireland. The new sleeker product incorporates a slimmer frame design that maximises the view through the glass panels and provides flood protection up to 800mm in height and where the load criteria consideration is hydrostatic water head. This system has already been installed in mainland europe and in the uK in south Wales. The IbS glass wall flood protection system is an ideal solution where traditional floodwalls are undesirable and temporary barriers cannot be installed due to certain logistical circumstances. Providing not only a spectacular alternative, the glass flood wall systems' benefits also include interchangeability, easily replaceable parts and maintenance free. IbS glass wall flood defence systems have been installed around the country, including in upton-upon-Severn in 2012, providing part of a solution to hold back floodwater from the river Severn and with the design enabling residents to view the river safely. The glass system at upton was successful in holding back the Severn on at least one occasion as the river rose during the winter flooding of 2013/14, said the company. www.ibsengineeredproducts.co.uk Tel: 01226 630015 Online and portable monitors launched Chelsea Technologies Group (CTG) has launched a new range of online and portable monitoring systems that provide significant advances in monitoring key parameters within the water industry. CTG has launched the bacti-Station, bacti-Wader, bOD-Station, bOD-Wader, algae-Station, algae-Wader, Oil-Station & Oil-Wader Systems. for monitoring misconnections within the network the new Cross-Check portable system is also now an option. www.chelsea.co.uk Tel: 020 8481 9019 options, false positives are reduced and efficiency increased as teams are sent only to validated leak locations. The unit is fully remotely programmable, including the ability to change sampling times and intervals. www.hwm-water.com Tel: 01633 489 479 Closed water treatment system in Denmark aarhus in Denmark faces many of the same challenges that are seen in places with a high population density including delivering clean water as effectively as possible. at Truelsjerg Waterworks a new system, supported by Grundfos Pumps, has been installed that is a closed water treatment system. The approach means there is now an entire, enclosed above ground water treatment system, with the entire water line and water treatment system enclosed and under constant pressure to ensure that no contamination can get to the water. This visionary solution utilises a wide range of Grundfos Pumps that supports all the processes needed for a pressurised closed water systems at every point from source through to delivery at the tap. Grundfos was chosen because of its range of stainless steel pumps, motors with built-in frequency control and a wide range of sensors that work to support the system. also, Grundfos supplied a range of pumps to support the centre's full-scale test facility that will be used by staff and research workers. www.grundfos.co.uk Tel: 01525 850000
