Tuff™ Thermal Mass Flow Meter (Gas) 24 VDC/85-240 VDC Accuracy 1% Reading + 0.5% Full Scale

Thermal Mass Flow Meter for Gas | Tuff™ Wide-Range Gas Measurement

The Tuff™ thermal mass flow meter delivers exceptional performance for measuring gas flow across extremely wide flow ranges. With typical turndown ratios of 100:1 and capability up to 1000:1, these meters provide unmatched versatility for low-flow to high-flow gas applications.

Industry-Leading Turndown Ratio

Measure from very low gas flows to maximum capacity with a single meter—eliminating the need for multiple instruments and reducing installation costs.

Ideal Gas Flow Applications:

• Boiler BTU measurement and energy monitoring
• Submetering and allocation systems
• Compressed air measurement and leak detection
• Flare gas monitoring and emissions tracking
• Mixed gas streams and blended gases
• Fugitive gas detection and recovery
• Nitrogen blanketing and inerting systems
• Flue gas and stack gas monitoring
• Hydrogen gas measurement (fuel cells, refineries, industrial)

Direct Mass Flow Measurement

Thermal mass flow meters measure true mass flow without requiring pressure and temperature compensation, providing accurate readings regardless of process condition changes.

Factory-Configured & Gas-Calibrated

Each Tuff™ thermal mass flow meter is custom-configured and gas-calibrated at our facility with a 4-6 week lead time. Our gas flow specialists will confirm:

1. Flow media (gas type and composition)
2. Flow rate range and turndown requirements
3. Process pressure and temperature conditions
4. Communication protocol (4-20mA, HART, Modbus, Profibus, Foundation Fieldbus)
