Marmonix MVF-2600 Vortex Air Flow Meter

The Marmonix MVF-2600 is an industrial vortex air flow meter for compressed air, gas, steam, and liquid lines. Compared with the thermal-mass MTF-4300 nitrogen gas flow meter, choose the MVF-2600 when you need a Karman-vortex meter that covers liquid, gas, and steam with flange or insertion mounting rather than a thermal gas-only design.

MVF-2600 vortex flow meter highlights

What the MVF-2600 delivers in compressor rooms and process lines:

• Flange DN15–DN300 or insertion DN100–DN2000 for flexible pipe sizes
• Typical accuracy about ±0.75% of reading (liquid) and ±1.0% (gas/steam)
• Medium temperature options up to about 350 °C (−20 to +100 / +250 / +350 °C classes)
• IP65 protection with Ex d IIB T6 Gb explosion-proof class
• Outputs: 4–20 mA, pulse, and RS485; 24 VDC or 3.6 V lithium power
• SS304 / SS316 body with modular digital converter for serviceability

Where teams use the MVF-2600 air vortex meter

Typical MVF-2600 use cases include:

• Compressed-air networks — compressor discharge and ring-main monitoring
• Utility gas & steam — plant utilities where vortex sensing fits the medium
• Process liquids — clean liquids in flange sizes DN15–DN300
• Large ducts/pipes — insertion probes on DN100–DN2000 lines

MVF-2600 vortex meter questions

What pipe sizes does the MVF-2600 cover?

Flange and flange-card versions cover about DN15–DN300; insertion versions target about DN100–DN2000, so one family spans small lines and large ducts.

When should I choose the MVF-2600 instead of the MTF-4300?

Choose the MVF-2600 for Karman-vortex measurement of liquid, gas, or steam with flange/insertion hardware; pick the MTF-4300 when you specifically need a thermal mass meter for nitrogen or similar gases.

Does the MVF-2600 support 4–20 mA and RS485?

Yes — typical outputs include 4–20 mA (two-wire), pulse (three-wire), and RS485 for PLC or SCADA integration.
