Complex applications

Industrial measurement demands more than an off-the-shelf meter

Industrial flow measurement is where application knowledge matters most. High-solids slurries, chemically aggressive media, abrasive flows, extreme temperatures, and challenging installation environments all require careful instrument selection, appropriate materials, and correct installation practice. Choose the wrong meter for the application and you're looking at rapid wear, inaccurate data, or a system that doesn't survive its first season.

NZ Flow Group specifies and supplies flow measurement solutions for industrial applications across New Zealand, drawing on hands-on experience with dredging, marine, water treatment, food processing, and trade waste applications. We match the instrument to the process, not the other way around.

Applications we work in

Dredge slurry High-solids abrasive flows including cutter suction dredge applications in marine environments
Trade waste discharge Industrial discharge metering to consent conditions, accurate measurement for reporting to council
Water treatment Process flow measurement across water treatment plant inputs, outputs, and internal transfer points
Industrial process water Cooling water, wash-down systems, and process intake metering for manufacturing operations
Marine environments Saltwater-tolerant instrumentation for port, harbour, and offshore applications
Bespoke applications If your application doesn't fit a standard solution, talk to us, we'll specify from first principles
Case example

Cutter suction dredge, marine slurry measurement

NZ Flow Group has specified flow and density measurement systems for cutter suction dredge operations in marine environments, including high-abrasion slurry at 30–60% solids by weight in seawater service on DN200 pipework.

Applications like these require electromagnetic magmeters rated for abrasive media. We work through the full specification, materials, liner selection, flange ratings, signal processing, and compliance with NZ regulatory requirements.

Why non-nuclear matters in NZ

Nuclear densitometers are heavily regulated in New Zealand

Under the Radiation Safety Act 2016, nuclear density measurement devices require WorkSafe NZ licensing, ongoing regulatory compliance, and specialist handling. For most industrial applications in New Zealand, non-nuclear ultrasonic slurry density meters are a practical and cost-effective alternative, and our preferred recommendation for new installations.

Our approach

Specification first, then supply

We work through the application before we recommend a product. For industrial projects, that process matters.

1

Application review

We start with the process conditions, fluid type, solids content, temperature, pressure, pipe size, flow range, and installation constraints. Getting these right determines everything that follows.

2

Instrument selection

We recommend the most appropriate meter technology and manufacturer for the application, and document our reasoning. For industrial applications, we produce a formal purchase specification you can use for vendor tendering.

3

Supply and installation

We source from our preferred vendor network, including Krohne, Endress+Hauser, Siemens, ABB, and Yokogawa, and carry out installation with NZ MechTech handling any pipework and fabrication work.

4

Commissioning and documentation

We commission on-site, confirm performance against specification, and hand over full documentation including installation records and compliance certificates where required.

Preferred vendors

We work with the instruments that perform

For industrial applications, we specify and supply from an established network of proven manufacturers, selected for performance in demanding conditions, not just price.
