Compressed Air Flow Measurement Solutions

Flowquip supplies a comprehensive range of air flow meters and compressed air flow measurement systems for industrial, commercial, and energy management applications. Whether you need to monitor compressed air consumption, measure process air flows, identify system leaks, or improve energy efficiency, we can provide a solution tailored to your application.

Compressed air is often referred to as the fourth utility and can be one of the most expensive energy sources within a manufacturing facility. Accurate air flow measurement helps operators reduce energy costs, identify wastage, optimise compressor performance, and improve overall system efficiency.

The choice of air flow meter depends on several factors including pressure, temperature, flow rate, pipe size, installation requirements, available power supply, and required accuracy. Flowquip's experienced engineers can help specify the most suitable technology for your application.

Types of Air Flow Meters

Thermal Mass Flow Meters

Thermal mass flow meters are one of the most popular technologies for compressed air measurement. They directly measure mass flow and are unaffected by changes in pressure and temperature, making them particularly suitable for monitoring compressed air consumption and energy usage.

Available as inline or insertion-style meters, thermal mass flow meters provide high accuracy across a wide flow range while offering both flow rate and total consumption measurement.

Key benefits include:

  • Direct mass flow measurement
  • Ideal for compressed air monitoring
  • Wide turndown range
  • Low pressure loss
  • Flow and total consumption display
  • Pulse and 4-20mA outputs
  • Suitable for leak detection and energy audits

Flowquip's VA520 compressed air flow meter offers excellent accuracy, simple installation, and integrated data logging options for industrial compressed air systems.

Variable Area Flow Meters

Variable area flow meters provide a simple and cost-effective solution for air flow measurement where a local visual indication is sufficient.

These meters are suitable for flow rates from a few cc/min up to 1,500 m³/hr and typically offer accuracies between ±3% and ±5% of full scale. They are particularly useful for laboratory, process, and low-cost monitoring applications.

Vortex Flow Meters

Vortex flow meters provide reliable air and gas flow measurement without the use of moving parts. Their robust design makes them ideal for industrial applications requiring long-term reliability and low maintenance.

With flow turndown ratios of up to 30:1 and measurement accuracies typically between ±1% and ±2%, vortex meters are well suited to compressed air distribution systems and process gas monitoring.

Coriolis Flow Meters

For the highest levels of accuracy, Coriolis flow meters provide direct mass flow measurement regardless of changes in pressure, temperature, or gas density.

These meters are capable of delivering accuracies better than ±0.5% and are often used in critical process applications, calibration systems, research facilities, and high-value gas measurement installations.

Benefits include:

  • Exceptional measurement accuracy
  • True mass flow measurement
  • Unaffected by pressure or temperature changes
  • Wide operating range
  • No flow conditioning requirements
  • Suitable for demanding industrial applications
