124 Transmitter Configuration and Use: Series 1000 and 2000 Transmitters
Troubleshooting continued
Inaccurate flow rate or batch total Bad flow calibration factor Verify characterization. See
Section 6.2.
Inappropriate measurement unit Check configuration. See
Section 10.19.
Bad sensor zero Rezero the flowmeter. See Section 5.5.
Bad density calibration factors Verify characterization. See
Section 6.2.
Bad flowmeter grounding See Section 10.13.3.
Slug flow See Section 10.16.
Problem with receiving device See Section 10.15.
Wiring problem Verify all sensor-to-transmitter wiring
and ensure the wires are making good
contact.
Inaccurate density reading Problem with process fluid Use standard procedures to check
quality of process fluid.
Bad density calibration factors Verify characterization. See
Section 6.2.
Wiring problem Verify all sensor-to-transmitter wiring
and ensure the wires are making good
contact.
Bad flowmeter grounding See Section 10.13.3.
Slug flow See Section 10.16.
Sensor cross-talk Check environment for sensor with
similar (±0.5 Hz) tube frequency.
Plugged flow tube Check drive gain and tube frequency.
Purge the flow tubes.
Temperature reading significantly
different from process temperature
RTD failure Check for alarm conditions and follow
troubleshooting procedure for indicated
alarm.
Verify “Use external temperature”
configuration and disable if appropriate.
See Section 9.3.
Temperature reading slightly different
from process temperature
Temperature calibration required Perform temperature calibration. See
Section C.4.
Unusually high density reading Plugged flow tube Check drive gain and tube frequency.
Purge the flow tubes.
Incorrect K2 value Verify characterization. See
Section 6.2.
Unusually low density reading Slug flow See Section 10.16.
Incorrect K2 value Verify characterization. See
Section 6.2.
Unusually high tube frequency Sensor erosion Contact Micro Motion. See
Section 10.3.
Unusually low tube frequency Plugged flow tube Purge the flow tubes.
Unusually low pickoff voltages Several possible causes See Section 10.24.5
.
Unusually high drive gain Several possible causes See Section 10.24.3.
