DEECO | "In the know about water flow"

Craig Ramsay Managing Director

This year we continued to see the introduction and development of many new products from our international suppliers. The rate and speed of R&D development and market availability seems to increase and the ability for Deeco to train in these new product features, gain supply and

make them available to our customers is an increasing challenge we must all meet in this world of technological expansion. Deeco has increased its rate of training and introduction to market of new products, and where ever possible negotiated with suppliers shortened supply chains, so that more product diversity can be available within an acceptable time frame and cost. In addition Deeco appointed Alexandre Angileri who has an extensive background in Irrigation design and field application in most of our irrigation products, as well as qualifications in marketing. Through this collaboration, our aim is to provide you, our customers, with ability to access more product information and their application detail more easily

from both Deeco and our suppliers. The first signs of these changes are evident in the design of this newsletter, our easy to use and download price list and of course the new interactive Deeco website. 2012 will continue to see Deeco expand our product range and services, so please do regularly look over our constantly evolving website to remain current with what is

available and just as importantly, the CURRENT performance specifications of our products.

With a long and growing list of successful New Zealand installations, Deeco have the experience to offer the right solution for your intake screening needs or


Johnson High Capacity Intake Screens solve many problems with debris and aquatic life entrainment at intakes while meeting or exceeding common resource consent conditions for surface water intakes. Johnson Passive Intake Screens are designed and constructed for efficient delivery of raw water at a very low and uniform inlet velocity, suspended solids or aquatic life are not SUCKED toward the screen surface eliminating regular maintenance regimes while protecting aquatic life from harm.


Johnson Screens® patented internal flow modifier

Secondary Flow Modifier

Primary Flow Modifier


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 intake sequentially or at regular intervals. The system can be manually or automatically operated.

Electromagnetic Flow Meter

EuroMag | Electromagnetic Flow Meter The EuroMag 2200/2500 series of electromagnetic sensors represent new technology for accurate measurement in water reticulation and process applications. This new generation sensor incorporates improvements to the signal protection as well as the magnetic distribution elements to create a unique electromagnetic field profile that ensures accuracy in turbulent, transitional, and laminar flow regimes. These new extended linearity EuroMag meters are capable of measurement in a range of more than 1000:1 without the aid of linearization software.

Data Transfer: EuroMag meters can be specified complete with the successful low cost CommCell 4 data telemetry station for automatic data delivery via GSM mobile network. For assistance and information on the water meters products, please contact us.



The meters are fitted with EuroMag’s latest low power consumption electronic multiple output MC608 model transmitter with either mains or battery powered options. The transmitter is IP67 rated when mounted on the meter or in an application with flooding potential the transmitter can be remote mounted with an IP68 rating for continuous underwater use to a depth of 10 meters. The transmitters large LCD backlit display provides full data interface via the 4 push buttons located below the display including Volume, Totalizers, Flow rates, Battery condition, flow direction, alarms, data logging, Serial output for device control, remote reading or output to telemetry is standard, as is the in­built 4 megabyte 200,000 lines 5 parameters per line data logger function.


• Battery powered version with a working life of up to 10 years (MC608B). • Battery replaceable in field. • Built­in data logger with fully programmable parameters. • Total management of power consumption with automatic sleep function. • IrDA interface for programming communication with laptop. • MODBUS RTU interface for communication on RS 485. • All configuration, totalizer and data logger values are stored even in case of power failure. • Multi­level password system to guarantee accessibility protection. • Submersible IP68 rating with remote mount.

Main Features

Meter with MID pattern approval acc. to annex MI001. Pattern approved (75/33/EEC).




Unique measuring range. High overload capability.

Metrological calss C acc. to 75/33/EEC in horizontal installation

Meter body in short (WP) and long (WS) overall length acc. to DIN 19625 and EN 14154 available. Used materials are temperature resistant up to 70°C. Register prepared for HRI­Mei pick­up. Use of optical pulser type OD is still possible. NO requirement for up and downstream straight pipe length

Advanced Metering Infrastructure (AMI Metering)

Automatic Meter Reading (AMR)


The Meistream Plus hydrodynamic meter ensures delivery of the highest accuracy in critical revenue and district metering applications. The Meistream Plus revolutionary rotor design provides starting flow characteristics 2.5 to 5.3 times better than standard Class B bulk water meters.

The resulting increase in low flow registration is critical to effective leak detection programmes, or commercial consumption metering. The proven performance commonly delivers a payback period as little as 2 months when compared with Class B meter costs and performance.
