    Tee fitting collector to connect two inlets. IFT-P monitors the airflow for both inlets. The analysis chamber consists of an optical chamber crossed by a laser beam, through which the air sample passes. Inside, a photoelectric sensor measures the amount of laser-produced light reflected by the particles of smoke as they pass through.
  • Page 6 1.3 Flow monitoring The monitoring system checks for any blockages, disconnections or gaps in the piping, making sure that the airflow level is not above or below the set thresholds. The flow thresholds are linked to the airflow specified during standardisation. Flow standardisation establishes the exact amount of air for that system during normal operation and sets this flow value to 100%.
