A035 Meter Verification
Aborted
114
Possible cause
The transmitter is not receiving
enough power.
This alert will not clear until you cy-
cle power to the meter.
A meter verification test is in pro-
gress, with outputs set to Fault.
The signal from the sensor pick-
off(s) is insufficient. This suggests
that the sensor tubes or vibrating
elements are not vibrating. This
alert often occurs in conjunction
with Alert 102.
The meter verification test did not
complete, possibly because of a
manual abort.
Micro Motion Model 2700 Transmitters with FOUNDATION Fieldbus
Recommended actions
• Check the wiring between the transmit-
ter and the core processor, then cycle
power to the meter.
• Check the wiring of the transmitter,
then cycle power to the meter.
• Verify that the transmitter is receiving
sufficient power.
- If it is not, correct the problem and
cycle power to the meter.
- If it is, this suggests that the trans-
mitter has an internal power issue.
Replace the transmitter.
• Allow the procedure to complete.
• Check for air in the flow tubes, tubes
not filled, foreign material in the tubes,
coating in the tubes, or other process
problems.
• Check for foreign material in the proc-
ess gas or fluid, coating, or other proc-
ess problems.
• Check for fluid separation by monitor-
ing the density value and comparing
the results against expected density val-
ues.
• Ensure that the sensor orientation is ap-
propriate for your application. Settling
from a two-phase or three-phase fluid
can cause this alert even if the flow
tubes are full.
• Verify that process conditions are sta-
ble, then retry the test.
• Contact customer support.
