OUR CALIBRATION SYSTEMS
01
We design each system around your meters, test medium, size and flow ranges, available space and throughput. From a compact bench to a fully automatic installation, we configure the test lines, automation and CALFLOW software to suit the way your laboratory works.
02
We select the reference method and instruments around your accuracy and calibration uncertainty requirements. Gravimetric, volumetric and comparison approaches are matched to the application, with integrated controls and CALFLOW data capture and reporting to support consistent, repeatable testing.
03
We bring robust mechanical construction, instrumentation and controls together in a complete working system. We build for regular laboratory use and support your team with commissioning, training and service, so you have dependable equipment and practical support beyond installation.
Test water meters through their operating life.
We manufacture type test benches for 10+ tests dor domestic water meters, including accuracy, endurance, temperature, flow disturbance, pressure loss and static pressure
Bring gas meter calibration to a compact bench.
We build MINI-GASCAL for domestic gas meter testing where a smaller laboratory footprint matters with pneumantic clamping and automation to ensure faster calibration
APPLICATIONS
Whether you’re building a calibration laboratory, tracking plant water use, controlling a batch or monitoring a tank, we help you select and specify the right measurement solution.
We help you monitor domestic, industrial plant water use, treatment flow and discharge. For cost-conscious water and wastewater projects, we offer NAGMAG NEO, our economical electromagnetic flow meter model, selected to suit the liquid, conductivity and installation.
We build flow, water and gas meter calibration systems for laboratories, manufacturers and utilities. We configure the reference method, flow range, meter sizes and automation around the calibration uncertainty and throughput your laboratory needs. Customized to your application, needs and budget.
We help you measure steam and gas use across your plant. We review the medium, temperature, pressure and flow range to select vortex or thermal mass instruments for utility monitoring and process control. We also help with low flow measurement with our mass flow meters and controllers.
We help you batch and transfer liquids with NAGBINE turbine flow meters—from hygienic food and beverage processing to de-ionized water in pharmaceutical & chemical plants. Sanitary options support hygienic installations, while our turbine-meter skids measure water-tanker unloading and other compatible liquid transfers.

THINGS TO KNOW
Nagman Flow designs and manufactures calibration and testing systems, including flow, water, gas and level systems. Its industrial product range also includes flow meters and level transmitters.
Yes. System configuration depends on the meters, size and flow ranges, test medium, reference method, automation and installation. Share these requirements so the engineering team can review a suitable approach.
Yes. Use Technical RFQ for a flow meter, level transmitter or a complete calibration system. The selected product is carried into the form, and you can edit it before sending.
Start with the application, medium, range and installation location. For systems, include meter sizes, reference method, automation and any applicable standards. The Technical RFQ form keeps the more detailed questions together.
Start with the medium, measuring range and process conditions. For flow, include pipe size, conductivity or viscosity where relevant, and installation constraints. For level, include vessel dimensions, mounting, foam or vapour, and the required output.
No. An instrument accuracy specification and the uncertainty of a calibration result describe different aspects of measurement. State each requirement separately in your Technical RFQ, along with the range, reference method and applicable test conditions.
