FLOW METERS.
Flow Meter Supplier New Zealand — Expert Supply & Advice
Whether you're an irrigation farmer managing water consent compliance, a council engineer maintaining municipal infrastructure, or a plant manager keeping industrial processes on spec — getting the right flow meter matters. NZ Flow Group are New Zealand's flow meter specialists. We supply, advise on, and support a wide range of flow meters across irrigation, municipal water and wastewater, and industrial applications — nationwide.
We're not a catalogue. We're a team of specialists who understand the full picture: the brands, the applications, the compliance requirements, and the conditions your meter will face in the field. If you're not sure what you need, that's exactly where we come in.
Flow meters for every NZ industry
No two applications are the same. The right flow meter for a Canterbury irrigation scheme looks very different to what a wastewater treatment plant or a food processing facility needs. We work across all three sectors and understand the specific demands, regulations, and performance requirements of each.
Irrigation
Industrial
Municipal
Irrigation flow meters
Water is one of New Zealand's most regulated resources, and irrigation consent holders are under increasing pressure to measure, record, and report their water takes accurately. Under the National Policy Statement for Freshwater Management (NPS-FM) and Environment Canterbury (ECan) consent conditions, your flow meter must be installed correctly, verified to within ±5% accuracy, and re-verified every five years.
NZ Flow Group supplies irrigation flow meters that meet these requirements from day one. We'll help you choose a meter suited to your pipe size, flow rates, and site conditions — and because we also offer installation and verification services in Canterbury, we understand what works in the field, not just on paper.
Common irrigation applications:
Surface water and groundwater takes
Pump outlet measurement
Mainline distribution monitoring
Pivot and border dyke systems
Municipal water and wastewater flow meters
Councils and water utilities across New Zealand rely on accurate flow measurement for billing, network management, leak detection, and regulatory reporting. The stakes are high — inaccurate meters mean inaccurate data, and inaccurate data has real consequences for infrastructure planning and compliance.
We supply flow meters suited to the demanding conditions of municipal water and wastewater networks: high-cycle operation, variable flow rates, and the need for long-term reliability with minimal maintenance. We have established working relationships with the majority of local and district councils in and around the Canterbury region, and supply meters to municipal customers nationwide.
Common municipal applications:
Bulk water supply metering
Reticulation network monitoring
Wastewater treatment plant flow measurement
District metering area (DMA) monitoring
Pump station flow measurement
In industrial settings, flow measurement is often tied directly to process quality, product consistency, and operational efficiency. A meter that drifts out of spec doesn't just affect compliance — it affects your product and your bottom line.
We supply flow meters for a wide range of industrial applications across New Zealand, from food and beverage processing to manufacturing and chemical handling. We'll help you match meter technology to your process fluid, pipe material, flow range, and communication requirements.
Common industrial applications:
Process water and cooling water measurement
Food and beverage production
Chemical dosing and transfer
Utilities metering (compressed air, steam, water)
Wastewater and effluent monitoring
Industrial process flow meters
A Selection Of The Most Common Flow Meter Types We Supply
There's no single flow meter that's right for every application. The technology you choose depends on your fluid type, pipe size, required accuracy, budget, and site conditions. Here's a plain-English overview of the main types we work with.
Electromagnetic flow meters — or mag flow meters — are the most widely used flow meter type across irrigation, municipal, and industrial applications in New Zealand, and for good reason. They use electromagnetic induction to measure flow with no moving parts, which means they're highly reliable, accurate, and low maintenance over their working life.
Mag flow meters are ideal for water, wastewater, and any conductive liquid. They handle dirty water well, cope with suspended solids, and are available in sizes from 25mm through to 2000mm diameter. If you're buying one flow meter for general water measurement in NZ, a mag meter is almost always the right starting point.
We supply mag flow meters from leading manufacturers including Siemens, Endress+Hauser, Krohne, and ABB — and we'll help you choose the right model and transmitter configuration for your specific application.
Electromagnetic Meters
Ultrasonic Flow Meters
Ultrasonic flow meters measure flow using sound waves — either by transmitting signals through the pipe wall (clamp-on) or via inline sensors. The clamp-on option is particularly useful for large diameter pipes (typically above 400mm) where cutting into the pipeline is impractical or expensive.
Because clamp-on ultrasonic meters don't require any pipe penetration, they're also a popular choice for temporary measurement, verification of existing meters, or situations where the process can't be interrupted. Inline ultrasonic meters offer high accuracy for clean water applications and are increasingly specified in municipal networks.
Mechanical or turbine flow meters use a rotating impeller driven by the flow of water to calculate flow rate. They're a cost-effective option for clean water applications with relatively stable flow rates, and are well established in the irrigation sector.
While they require more maintenance than mag or ultrasonic meters due to their moving parts, they remain a practical and affordable choice for many irrigation and straightforward water measurement applications — particularly where budget is a key consideration.

Independent, multi-brand advice
We're not tied to any single manufacturer. We work with the leading brands — Siemens, Endress+Hauser, Krohne, ABB, and others — and will recommend the best meter for your application, not the one that suits our margins. If you're not sure what you need, we'll ask the right questions and get you to the right answer.
Specialists, not generalists
Flow measurement is all we do. We understand irrigation consent requirements, municipal network demands, and industrial process challenges at a level that a general instrumentation catalogue simply can't match. That expertise shows up when it matters — in meter selection, installation guidance, and long-term performance.
NZ compliance knowledge
We understand the regulatory environment New Zealand flow meter users operate in — from ECan consent conditions and the NPS-FM to the New Zealand Water Measurement Code of Practice. When you buy a meter from us, you're getting advice from people who understand what your meter needs to do to keep you compliant.
End-to-end capability
For Canterbury customers, we offer the complete package: supply, installation, verification, and ongoing maintenance. For customers outside Canterbury, we supply the right meter with the guidance you need to get it installed and performing correctly.
Genuine local support
We're a Canterbury-based NZ business. When you call us, you talk to a specialist — not a call centre. We're invested in getting it right because our reputation depends on it.
