Tracer-gas leak testing method

When the tracer measurement ( also referred to as a trace gas detection or measurement of tracer gas ), the enriched air or an air flow with a small amount of tracer gas. Due to the dilution of this gas can be calculated by measuring the concentration in the drop of the effective volume flow and a leakage flow.

The diverse application possibilities of this method of measurement allow, among other things, the measurement of the efficiency of a ventilation system. The tracer gas method for the determination of air exchange in buildings is described in DIN EN ISO 12569 in detail. As tracer gases only minimal amounts of gas are used today, thanks to highly sensitive gas analyzers that have no physiological effect on humans.

Examples of the use of the tracer gas analysis

  • Volume flow measurement in air ducts
  • Measurement of building tightness
  • Leakage measurement in technical systems
  • Measurement of air exchange rate in accordance with DIN EN ISO 12569
  • Measurement of short circuits in remote devices
  • Measuring the volume flow in the space
  • Determination of the operating characteristic curve of the mixed air valve
  • Verification of flow regulators in the installed state
  • Noxious gas transmission / efficacy of suction
  • Measurement of smoke tightness of fire compartments / Measurement of smoke spread
  • Measurement of the exhaust air back into the share of the service entrance
  • Analysis of pollutant dispersion in the building
  • Tightness of closure flaps
  • Tightness of storage of dangerous goods
  • Tested the efficacy of Notlüftungssystemen
  • Checking the spread of germs in hospitals
  • Determination of air content in the fresh air
  • Leak detection of pipelines ( district heating pipeline, gas lines, ... )
  • Gas Technology
  • Fluid Mechanics
