4.3.1b Multi-channel error
If more than one channel is in error, the most likely cause is changes in process/flow conditions such as:
1. Excessive turbulence.
2. Discontinuities in fluid characteristics such as multi-phase flow, flashing, pockets of gas, presence of bubbles or solid
particles, cavitation or rapidly changing fluid type.
3. Extreme fluid properties, such as pressure or temperature.
4. Wax build-up inside the pipe.
5. Partially filled pipe.
After you have tried eliminating/correcting for any most likely causes mentioned above, if error still exists, also check:
1. Incorrect programming on Error Limits or flow condition changes that now make previous programming invalid.
2. Defective/Damaged cables, transducers, incorrect physical spacing, couplant, buffer or electronics.
In case you are unable to clear the errors, collect diagnostic data and parameter information for each channel in the
Diagnostics Data Table prior to calling your local sales or service center.
4.3.1c Viewing channel specific error/warnings
To indicate the health of the meter, PanaFlow™ LC has built-in Error codes. The Channel specific errors are very critical
in determining the corrective actions required. Figure 80 below shows the steps to view current channel specific errors/
warnings. The description of the Error Codes and the recommended actions are provided in Table 21 below.
