Proline t-mass B 150 – Thermal Mass Flowmeter for Gases
The Endress+Hauser Proline t-mass B 150 measures the mass flow of gases directly using the thermal dispersion principle, eliminating the need for separate pressure and temperature compensation. Ideal for compressed air, nitrogen, natural gas, and other industrial gas applications.
Key Features
- Nominal diameter: DN15 to DN150
- Direct mass flow measurement – no P/T compensation needed
- Accuracy: ±1.5% of reading
- Gas types: Air, N₂, O₂, CO₂, CH₄, H₂, and custom gas mixtures
- Process temperature: –40 to +200°C
- Process pressure: Up to 100 bar
- Communication: 4–20 mA HART, PROFIBUS DP, Modbus RS485
Applications
- Compressed air metering and energy management
- Natural gas and biogas measurement
- Nitrogen and inert gas monitoring
- Combustion air measurement
