Table 7: inLoop™ ACE Troubleshooting (Continued)
Issues Possible Causes Solutions
The sample container is not filling.
The external sand relief on the inLoop™
ACE may be set too high.
The poppet of the internal inlet and/or
outlet check valve may be damaged.
The sample inlet and/or outlet pressure is
inadequate for the actuation pressure.
The actuation pressure is inadequate for
the sample inlet and/or outlet pressure.
Check the setting on the external sand
relief and adjust as necessary. Note the
external sand relief should be set 50–100
psig above operating pressure.
Replace the poppet(s). See Section 3.2,
Maintenance, for instructions.
Ensure the sample inlet and/or outlet
pressure is appropriate for the actuation
pressure (Figure 8).
Ensure the actuation pressure is
appropriate for the sample inlet and/or
outlet pressure (Figure 8).
The sample container is filling too
quickly.
The inLoop™ ACE is not collecting the
correct sample volume.
The inLoop™ ACE may be set at a faster
sampling frequency than desired.
The external sand relief on the inLoop™
ACE may be set too low.
Welker recommends the Welker
Checkpoint™ Sample Bite Verification
Panel for verifying the sample volume of
the inLoop™ ACE. See Section 2.2,
Installing the Unit, for instructions on
adjusting the sample volume.
Adjust the inLoop™ ACE to sample at the
desired rate. Ensure that the calculations
used to determine the sample frequency
are correct (Figure 9).
Check the setting on the external sand
relief and adjust as necessary. Note the
external sand relief should be set 50–100
psig above operating pressure.
