A122 Pressure Overrange
(API Referral)
The line pressure is outside the
range of the API table.
• Check your process conditions against
the values reported by the device.
• Verify the configuration of the API refer-
ral application and related parameters.
See Section 10.10.
A132 Sensor Simulation
Active
Sensor simulation is enabled. • Disable sensor simulation.
A133 EEPROM Error (Dis-
play)
There is a memory error in the dis-
play module.
• Cycle power to the meter.
• Replace the display module.
• Contact Micro Motion.
A136 Incorrect Display
Type
An incorrect display module has
been installed on the device. This
may cause a safety violation in haz-
ardous areas.
• Replace the installed display module
with an appropriate display module.
10.7 Viscosity measurement problems
Viscosity measurement problems and recommended actionsTable 10-2:
Problem Possible causes Recommended actions
Viscosity reading er-
ratic
• Normal process noise
• Two-phase flow
• Deposition or coating, especially asphal-
tenes, on the tines
• Contaminants in the process fluid
• Vibration in the pipeline
• Increase the viscosity damping value.
• Check your process conditions.
• Check for two-phase flow, stratification, or
settling. Install a pump. Check for environ-
mental conditions that produce stratifica-
tion (e.g., a heat source).
• Increase back pressure to minimize bubble
formation.
• Clean the tines.
• Minimize vibration in the pipeline.
