Craig RamsayManaging DirectorThis year we continued to seethe introduction anddevelopment of many newproducts from ourinternational suppliers.The rate and speed of R&Ddevelopment and marketavailability seems to increaseand the ability for Deeco totrain in these new productfeatures, gain supply and

make them available to ourcustomers is an increasingchallenge we must all meet inthis world of technologicalexpansion.Deeco has increased its rateof training and introduction tomarket of new products, andwhere ever possiblenegotiated with suppliersshortened supply chains, sothat more product diversitycan be available within anacceptable time frame andcost.In addition Deeco appointedAlexandre Angileri who has anextensive background inIrrigation design and fieldapplication in most of ourirrigation products, as well asqualifications in marketing.Through this collaboration, ouraim is to provide you, ourcustomers, with ability toaccess more productinformation and theirapplication detail more easily

from both Deeco and oursuppliers.The first signs of thesechanges are evident in thedesign of this newsletter, oureasy to use anddownload price list and ofcourse the newinteractive Deecowebsite.2012 will continue to seeDeeco expand ourproduct range andservices, so please doregularly look over ourconstantly evolving website toremain current with what is

available and just asimportantly, the CURRENTperformance specifications ofour products.

Johnson Passive Intake Screens |

Focus on |Passive Intake Screens

The World's Most EfficientIntake System

Johnson High Capacity IntakeScreens solve many problemswith debris and aquatic lifeentrainment at intakes whilemeeting or exceeding commonresource consent conditions forsurface water intakes. JohnsonPassive Intake Screens aredesigned and constructed forefficient delivery of raw water at avery low and uniform inlet velocity,suspended solids or aquatic lifeare not SUCKED toward thescreen surface eliminating regularmaintenance regimes whileprotecting aquatic life from harm.

Johnson Screens® patented internal flow modifierHIGH EFFICIENCYAND LOW COSTSSecondary Flow Modifier

Primary Flow Modifier

The Most Efficient Intake ScreenSystem in the World – WHY?• Wedgewire construction• Greater open area and low headloss• High capacity performance• Dual pipe flow modifier• Uniform flow distribution across entire screen surface• Very low and controlled through slot velocity• Resistance to blocking• Static Screening ­ No moving parts• No collection or disposal of debris required• Compressed air backwash method• Project specific Hydroburst backwash design• Very low energy consumption compressor only• PLC control with remote integration capability• Design solutions for any intake application orenvironment

HYDROBURST™ BACKWASHAN AUTOMATIC CLEANING PROCESS

With a long and growing listof successful New Zealandinstallations, Deeco havethe experience to offer theright solution for your intakescreening needs

THE HYDROBURST™ SYSTEM:1. A compressor, which supplies compressed air, needed to

recharge the receiver tank.2. A receiver tank that stores the compressed air.3. A distributor system is required for multi­screen applications.4. A control panel, for manual or automatic operation.The typical backwash procedure cleans each water intakesequentially or at regular intervals. The system can be manuallyor automatically operated.

Focus on |Electromagnetic Flow Meter

The EuroMag 2200/2500 series of electromagnetic sensorsrepresent new technology for accurate measurement in waterreticulation and process applications. This new generation sensorincorporates improvements to the signal protection as well as themagnetic distribution elements to create a unique electromagneticfield profile that ensures accuracy in turbulent, transitional, andlaminar flow regimes. These new extended linearity EuroMagmeters are capable of measurement in a range of more than 1000:1without the aid of linearization software.

EuroMag | Electromagnetic Flow Meter

The meters are fitted with EuroMag’s latest lowpower consumption electronic multiple outputMC608 model transmitter with either mains orbattery powered options.The transmitter is IP67 rated when mounted on themeter or in an application with flooding potential thetransmitter can be remote mounted with an IP68rating for continuous underwater use to a depth of10 meters.The transmitters large LCD backlit display providesfull data interface via the 4 push buttons locatedbelow the display including Volume, Totalizers,Flow rates, Battery condition, flow direction,alarms, data logging, Serial output for devicecontrol, remote reading or output to telemetry isstandard, as is the in­built 4 megabyte 200,000lines 5 parameters per line data logger function.

MAIN FEATURES• Battery powered version with aworking life of up to 10 years(MC608B).• Battery replaceable in field.• Built­in data logger with fullyprogrammable parameters.• Total management of powerconsumption with automatic sleepfunction.• IrDA interface for programmingcommunication with laptop.• MODBUS RTU interface forcommunication on RS 485.• All configuration, totalizer and datalogger values are stored even incase of power failure.• Multi­level password system toguarantee accessibility protection.• Submersible IP68 rating with remotemount.

Partners for success. Sensus designs andmanufactures meters and systems in its ownfacilities, delivering an end­to­end approach thatstarts with project specification and design, andleads to manufacture and application by ourteams of qualified engineers and technicians.For more than a century, Sensus has been a keypartner for energy companies and utilities. Todaythe company is the measure of the future when itcomes to delivering advanced data collection andmetering infrastructure solutions.

"BECAUSE EVERYDROP COUNTS"The Meistream Plushydrodynamic meter ensuresdelivery of the highestaccuracy in critical revenueand district meteringapplications. The MeistreamPlus revolutionary rotordesign provides starting flowcharacteristics 2.5 to 5.3times better than standardClass B bulk water meters.

The resulting increase in low flowregistration is critical to effective leakdetection programmes, or commercialconsumption metering. The provenperformance commonly delivers apayback period as little as 2 months whencompared with Class B meter costs andperformance.
