PN 9000-133-VE, Rev U
Flow Sensor
Component
Function
Overview
The aspirator creates a vacuum and pulls the process gas into the
analyzer. There are two paths for the gas to take.
• Immediately back to the process gas.
• Through the sample loop, past the cell and/or combustible
detector.
Calibrated at the factory, the flow sensor (see Figure 1-3 for
location) measures the sample flow through the sample loop.
The flow measurement is updated every 90 seconds. This delay
is used to allow the analyzer to effectively auto-zero to prevent
false alarms.
