Thermal mass flow meters are designed for industrial gases, dry/clean air, Nitrogen applications, such as compressed air, venting air, aeration, process protection Nitrogen, combustion air, etc. They are widely employed in petrochemical plants, power generation, environmental monitoring, and food/beverage production
Thermal mass flow meter directly measure mass flow, eliminating the need for separate pressure and temperature compensation instruments, which simplifies installation and reduces costs. It offers high accuracy and high turndown ratio (typically 100:1 or more), allowing them to precisely measure the wide variations in gas mass flow rates.
With no moving parts, thermal mass flow meter is durable, require minimal maintenance, and are less susceptible to clogging or wear from dirty/wet biogas or air streams compared to other flow meter technologies.
The insertion type flow meter cause virtually no pressure drop in the pipeline, which conserves energy and reduces wear on blowers or compressors. The simple installation of insertion type flow meter via a hot-tapped ball valve does not require pipe section cuts making them a cost-effective solution for monitoring gas flows in large-diameter pipes.

Industrial Applications:
- Compressed Air System Monitoring:
Widely used in industrial applications to measure compressed air for system auditing, leak detection, and energy management, offering direct mass measurement without pressure or temperature compensation. Key applications include monitoring main header pipes, sub-metering department usage, and optimizing compressor performance. - Aeration Control and Optimization:
A typical aeration process consumes up to 60% of a WWTP’s total energy. Thermal mass flow meter precisely measure the airflow into aeration basins, allowing operators to regulate the air supply to meet the optimal dissolved oxygen (DO) content for bacterial growth. This precise control avoids over-aeration (which wastes energy) or under-aeration (which compromises treatment quality), leading to significant energy cost reductions and more efficient operation. - Biogas Production Monitoring:
Anaerobic digesters produce biogas is a valuable renewable energy source. Thermal mass flow meter measure the flow of this biogas, which can be captured and used as fuel in co-generators to produce electricity and heat for the plant, thus offsetting high energy bills. Accurate measurement is essential for:- Efficiency tracking: Monitoring biogas production helps evaluate digester performance and optimize the digestion process.
- Combustion control: Ensuring the correct fuel-to-air ratio for efficient and safe combustion in engines or boilers.
- Emissions reporting: Tracking methane (a potent greenhouse gas) emissions for environmental compliance and potential carbon credits.
