Nitrogen Flow Monitoring
Precise flow and consumption measurement for reliable nitrogen gas supply in industrial applications
Nitrogen gas is a vital resource in many production and laboratory processes. It provides an inert atmosphere that prevents oxidation, contamination, and unwanted reactions. Whether used for blanketing, purging, packaging, or heat treatment, controlling the nitrogen gas flow ensures efficiency, safety, and consistent product quality.
SUTO iTEC develops advanced nitrogen gas flow meters that provide accurate and reliable measurement. Using proven thermal mass technology, they measure mass flow directly, independent of pressure and temperature, giving users full control over their gas consumption and process performance.

Frequently Asked Questions about Nitrogen Gas Flow Meters
What is a nitrogen gas flow meter
A nitrogen gas flow meter measures the mass flow of nitrogen gas through a pipe or process line. SUTO iTEC meters use the thermal mass principle, providing direct and highly accurate mass flow measurement without the need for temperature or pressure compensation.
How do I select the right model
The ideal model depends on the pipe size, flow range, installation type, and communication requirements.
- Inline models are used for fixed and smaller gas lines.
- Insertion meters fit larger pipelines and retrofit installations.
- Compact models like the S415 are perfect for point-of-use and decentralized monitoring.
How should the meter be installed
Most SUTO iTEC meters can be installed in any position. Follow the product manual for best accuracy.
- S401 insertion meters can be installed under pressure using a ball valve.
- S421 inline meters should follow the indicated flow direction.
- S415 and S418 have built-in flow conditioners and require no long straight pipe sections.
- S453 heavy duty models are suitable for harsh environments and any mounting orientation.
Is remote monitoring possible
Yes. SUTO iTEC flow meters connect via Bluetooth to the S4C-FS App or to data loggers such as the S331. For central control, they can integrate into SCADA or PLC systems using Modbus RTU, Modbus TCP, or M-Bus protocols.
What maintenance is required
Maintenance is minimal. Regular calibration and gentle cleaning of the sensor element ensure long-term accuracy.
