The purge fitting is used to detect gas levels in a pressurized gas stream from a
pipeline or vessel being purged.
1. Start up the Gas Tracer as described in “Start Up, Normal Mode” on page 25.
2. Connect the purge tee fitting to the Gas Tracer’s quick connect inlet fitting.
3. Insert the sample port into the flowing gas. The vent port will allow any excess
gas to release to the atmosphere to avoid damage to pump or sensors.
