Symptoms
Symptom: Transmitter does not power up.
Possible Causes Recommended Action
• No power or inadequate power
• Blown fuse (AC Model only)
• Display ribbon cable not seated
properly
• Measure voltage at the power terminals and check that the voltage matches the labels by the
power terminals.
• Check the fuse near the power terminals. If fuse is blown, verify the voltage and polarity is
correct and reset the fuse.
• Inspect ribbon cable connections. LED’s on power board will light up with no LCD display.
• Replace the transmitter if the above actions do not resolve the issue.
Symptom: Flow reading appears to be incorrect.
Possible Causes Recommended Action
• Incorrect positioning of
transducers
• Poor contact between
transducers and pipe
• Poor placement of transducers
• Low signal strength
• Process loop issues
• Incorrect pipe settings
• Meter not calibrated
• Display not set up correctly
Refer to the Transducer Mounting Configuration section for details on proper installation.
At the transducer:
• Verify that the spacing of the transducers is set correctly. On most transducers, a scribe mark on
the side of the transducers indicates the point of measurement—NOT from the end points of
the transducers.
• Verify that the transducers are aligned correctly. For Z-Mount, verify the transducers are 180°
from each other.
• Make sure there is a good contact between the transducers and pipe and a thin coat of acoustic
coupling is applied. For integral mount, check for over-tightening of the transducers.
Process loop and general location:
• Make sure the transducers are on the sides of the pipe and NOT on the top of the pipe.
• Check that the transducers are NOT located at the highest point in the loop where air may
accumulate.
• Check that the transducers are NOT on a downward flowing pipe unless adequate downstream
head pressure is present to overcome partial filling or cavitation.
• Check that the transducers have adequate straight pipe upstream and downstream.
• Check process loop for entrained air or particulates which will impact the flow readings.
• Pipes may develop scale, product build-up or corrosion over time. As a result, the effective wall
thickness may be different than a new pipe and wall thickness or liner parameters may need to
be adjusted.
At the transmitter:
• Verify that pipe parameters match the installation.
