Features
● True Mass Flow Measurement: Direct reading of gas mass flow or standard volume flow – no need for temperature or pressure compensation.
● Extremely Wide Turndown Ratio: Measures flow rates from 0.1 Nm/s up to 100 Nm/s, ideal for both high-flow processes and gas leak detection.
● No Moving Parts: Sensor contains no moving or pressure-sensing components, ensuring long service life and excellent vibration resistance.
● Vibration-Immune: Measurement accuracy unaffected by mechanical vibration or installation conditions.
● Easy Installation & Maintenance: Optional non-stop production installation and maintenance (special customization required).
● Fully Digital Design: All-digital circuit processing ensures high measurement accuracy and simplified maintenance.
● Industrial Communication: RS-485 interface standard, supporting factory automation and DCS/PLC system integration.
Applications
Suitable for accurate metering of O₂, H₂, N₂, air, LPG, biogas, blast furnace gas in industrial processes, with stable performance under vibration and variable conditions.
