Compliance with National Regulations.
Data Loggers & Telemetry.
We supply a range of mechanical, ultrasonic, and electromagnetic water meter models to suit the needs of your sites and water takes. They are all compatible with our telemetry hardware to communicate the data back to you no matter how remote the location thanks to a combination of cellular and satellite connectivity.
Our software platform is then able to process the data retrieved to produce insights into your water usage, as well as providing data exports to meet your reporting requirements to local councils around surface water takes and bores.
We have also additional hardware options available for soil moisture and weather monitoring.
Our data loggers have an internal data storage capacity compliant with The New Zealand Water Measurement Code of Practice (COP)
Flow Meter Verification & Validation.
Local authorities require ground and surface water users to track and record water volume takes. We help you monitor these takes, using suitably installed & specified flow meters incorporated into the system design. Provision has to also be engineered into that design to be able to verify that the flow meter is operating within a tolerance of +/- 5% when compared to a verification flow meter.
NZ Flow Group’s team and equipment are Blue Tick accredited by Irrigation NZ to complete verifications, host data and install water meters.
ECAN, Canterbury's local governing body, specifies that an Ultrasonic Clamp-On type flow meter is used to complete flow meter verifications within the region.
Frequency of Verifications
Mechanical meters - Two years between verifications as per industry standard
Magnetic & ultrasonic meters - Five years between verifications as per Resource Management (Measurement and Reporting of Water Takes) Regulations 2010
New meters & telemetry - verified, and documents supplied to Council within six months of installation
Validation
Ensures the function of a system meets the stated functional intent. Our validation services are fundamental to your processes running efficiently! We offer a data logged flow report of any areas of your process so you can demonstrate precisely where all the water goes within your plant and/or network and how much.
Flow Meter Calibration.
Calibration ensures the measurement accuracy of an instrument compared to a known standard. Our portable Flexim Fluxus F601 meters are sent away for calibration every year. This involves our meters being compared to an IANZ accredited flow rig under known and fixed conditions for a specified amount of time. They are then certified to verify installed flow meters where compliance-driven testing is required.
Mechanical Work
Our mechanical engineering division NZ MechTech offers solutions to meet flow meter installation requirements. Disturbances in flow caused by pump proximity, bends, valves and changes in pipe size can greatly effect the accuracy when measuring water flow. In some cases these issues can’t be completely eliminated. Attention is then given to minimise the possibility of flow disturbances and increasing the accuracy of the flow meter.
Data Hosting
We utilise a cloud-based asset management platform that is asset and vendor agnostic. This allows us to integrate both new and existing smart meters into our system. It provides you with easy to use dashboards for displaying your data in a way that works for you.
Our software platform is customisable and scalable. This means you have the information you need available when you need it, regardless of how big or small your organisation. Built in checks and tools for data quality assurance and reporting ensure we provide you a fully compliant data software platform that will make it easy to prove you are meeting the requirements and regulations set by your local water controlling authority.
Electronic Verification
An Electronic Verification uses brand specific test equipment to check the health of the installed mag flow meter. A series of electronic tests are carried out which are compared to factory test results which generate either a pass or a fail. Once completed, an Electronic Verification Certificate can be generated. In most cases, these can be used as proof of accuracy for local, district and regional councils.
Verification schedules may also differ slightly but generally, all mechanical meters need verifying every two years. Ultrasonic meters every 3 years and Electromagnetic meters every 5 years. The installation of new meters and associated telemetry equipment will require verification, and documents supplied to the council as soon as possible.
