198 Sentinel LNG User’s Manual
Cause: This error may be caused by the entry of improper programming data or by poor flow conditions and/or
excessive turbulence.
Action: Make sure the actual flow rate is within the programmed limits. Also, check the value entered into the
Error Limits option , as described on page 46. Refer to the sections on Fluid and Pipe Problems
(page 202) and on Transducer Problems (page 203) to correct any problems. If this error persists, and no
fluid or pipe problems appear to exist, consider enabling the Tracking Windows option.
9.2.5 E4: Signal Quality Error
Problem: The signal quality is outside the limits programmed in the Error Limits option of the User Program.
Cause: The peak of the upstream or downstream correlation signals has fallen below the correlation peak limit,
as set in the Error Limits option on page 46. This may be caused by a flowcell or electrical problem.
Action: Consult the factory.
9.2.6 E5: Amplitude Error
Problem: The signal amplitude exceeds the limits programmed in the Error Limits option of the User Program.
Cause: Solid or liquid particulates may be present in the flowcell. The error could also be caused by poor
coupling for clamp-on transducers.
Action: Consult the factory.
9.2.7 E6: Cycle Skip, Acceleration Error
Problem: The acceleration exceeds the limits programmed in the Error Limits option of the User Program.
Cause: This condition is usually caused by erratic flow conditions.
Action: Consult the factory.
