Pioneers in Compressed Air Drying and Filtering. Quality at a Fair Price. 

Tegnon has developed a cost-effective air flow sensor to meet the needs of the South African market.

Air Flow Sensor


Rising energy costs are driving organizations to evaluate their energy consumption. Research has shown that the most efficient way to reduce compressed air usage is to constantly determine consumption and react quickly to unexpected system changes.

The Tegnon air flow sensor continuously monitors compressed air usage and system efficiency. This high precision air flow sensor has been designed to accurately measure compressed air flow within industrial compressed air networks.

The Tegnon air flow sensor assists companies to:

  • Identify system inefficiencies.
  • Confirm the effectiveness of system improvements.
  • Ensure that efficiency improvements are maintained.

The air flow sensor can be connected to Tegnon's compressed air efficiency monitoring cloud platform. The platform records flow history in the cloud, and allows our clients to track flow performance on a continuous basis.

Features of our sensor include:

  • Real-time LCD display
  • Integrated RS485 Modbus RTU network card
  • Pressure and dew point tracking options
  • Integration to Tegnon cloud-monitoring platform
  • The ability to load custom calibration curves
