Durag D-FL 100 Volume Flow Measuring System

The DURAG D-FL 100 provides a suitability-tested and certified impact pressure system to measure velocity and volume flow of dry flue gas or process gas in pipes or ducts.

Features

  • Continuous measurement of velocity and volume flow
  • Double-sided installation for measurement over the entire duct diameter or cost-saving single-sided installation 
  • Robust and resistant probe material for use in aggressive gases or at high temperatures (optional)
  • Probe individually adapted to the application
  • Automatic back purging unit (optional)
  • Automatic internal self-test

Key Benefits

  • Certified for official emission monitoring
  • Precise measurement of velocity and volume flow even under demanding operating conditions
  • Space-saving and easy single-sided installation (optional)
  • Suitable for use in potentially explosive atmospheres (optional)
  • Suitable for use in hot gases

Applications

  • Continuous emission monitoring in hot or aggressive gases
  • Continuous emission monitoring in small to large duct diameters
  • Continuous emission monitoring in explosive atmospheres
  • Volume flow measurement for process control and process optimization
