Precise Measurement and Control Solution for Blast Furnace Gas, Oxygen, and Nitrogen Flow Rates in Metallurgical & Iron Industry Using Thermal Gas Mass Flow Meters

Thermal gas mass flow meters feature wide turndown ratio and no need of pressure & temperature compensation. Regular maintenance and standardized installation can effectively avoid inaccurate measurement and guarantee long-term stable operation.

Thermal gas mass flow meters feature fast response and high precision for clean small and medium gas flow, needing no temperature and pressure compensation. But they are vulnerable to contamination and limited in large flow measurement, suitable for precise industrial gas control rather than dirty gas or large-bore pipeline scenarios.

Customized for harsh marine environments with vibration, salt fog and wide temperature variation, this upgraded thermal mass flow meter adopts anti-corrosion and shockproof design. It realizes stable gas mass flow monitoring for ship engines, exhaust treatment and compressed air systems, complying with marine industry operation standards.

Brief Summary
Adopting fixed temperature difference control, this flow meter features fast response and high measuring accuracy without temperature and pressure compensation. It dominates mainstream MFC applications, yet it is vulnerable to pipeline contamination and is not fit for ultra-large gas flow conditions.
