Thermal Mass Air Flow Meter

Faster, More Accurate Air Flow Measurement

Thermal Mass Flow Meters from Fox Thermal are a cost effective solution for industrial air flow measurement applications. Flow meters solve issues with:

  • Process control
  • Transient flow conditions
  • Energy consumption analysis

Advanced Thermal Mass Flow Meters

Improve Process Control

Industrial processes utilize air flow rate measurements to control and optimize production processes. Accurate flow rate measurement in key process stages ensures that quality output is maintained.

Wide turndown

Thermal Mass Flow Meters offer accurate flow measurement at both low and high flow rates. The versatility of this technology coupled with features like calibration validation provides confidence in process controls.

Reduce Energy Costs

Energy costs can be reduced in combustion applications by tuning the air-to-fuel ratio. Further cost reduction can be achieved by monitoring flow rates over time to detect system leaks and inefficiencies.

Precision Air Flow Measurement Instruments

With air flow measurment in an industrial process, costly air and gas leaks can be identified on a system-wide scale. This is important when considering that leaks are frequently a significant source of lost energy, sometimes wasting up to 30% of output in standard cubic feet or liters per minute of airflow.

Fitting your systems with accurate thermal mass air flow meters is an effective first step in controlling energy costs. High power costs force many plant managers to improve control of dryers, compressors, blowers, and other airflow for industrial processes.
