6. Collect a sample from the sample outlet to ensure that the sample volume collected is the same as the desired sample
volume.
Welker recommends the Welker Checkpoint™ Sample Bite Verification Panel for use with this unit.
2.6 Purging the Unit
The purge tube allows the sampler to be completely evacuated of sample from the inlet to the sample container. Automated
purging can be achieved with the Welker PNP Plug & Purge Panel.
To prevent cross-contamination between samples, Welker recommends that the inFlow™ ACE be evacuated, or purged,
following each sample batch to inject all sampled product remaining in the unit into the sample container.
1. Connect an appropriate customer-supplied nitrogen or other inert gas supply to purge valve P ( Figure 1 ).
Welker recommends using nitrogen or helium as the inert gas supply.
2. Set the inert gas supply pressure to approximately 50 psig above the external relief on the inFlow™ ACE.
Prior to purging the unit, ensure that the purge pressure (i.e., the purge setting minus the external adjustable relief setting) does
not exceed the pressure rating of the sample container.
3. Turn ON the inert gas supply.
4. Open purge valve P ( Figure 1 ).
5. Allow product in the inFlow™ ACE to drain. Monitor the sample container for under- or over-purging.
If no inert gas is heard entering the sample container, the purge pressure has been set too low and previous product remains in
the sampler.
If more than a burst of inert gas is heard entering the sample container, the purge pressure has been set too high and the
operator risks overpressurizing the sample container.
6. Turn off the inert gas supply.
7. Close purge valve P ( Figure 1 ).
8. Disconnect the inert gas supply from purge valve P ( Figure 1 ).
