4.3 Flow Errors (E-Errors)
4.3.1 General Guidelines for Troubleshooting Flow Errors with Error codes
If the Error code on the LCD or Vitality PC software indicate E22: SingleChAccuracy or E23: MultiChAccuracy, refer to the
appropriate section below. Also, refer to Table 3 below for causes and recommended actions for each Error code.
4.3.1.1 Single Channel Error
If only one channel is in error, the most likely causes are:
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.
After you have tried eliminating/correcting for any most likely causes mentioned above, if error still exists, also check
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. Half-full pipe.
4.3.1.2 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.\
4.3.1.3 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 39 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 3 below.
