5.  MAINTENANCE

5.9 Troubleshooting

Although magnetic flowmeters rarely require maintenance, failures may occur when the
instrument is not operated correctly. This section describes troubleshooting procedures
where the cause of the breakdown is identified through receiver indication.

5.9.1

No Indication

Is an error being displayed? Check the converter display.

NO

YES

NO

NO

YES

NO

YES

NO

Is an error being

displayed?

Is anything else

being displayed?

YES

YES

Check whether the flowtube 
is filled with fluid.

Is the flowtube

full of fluid?

Remove the tube and 
inspect the inside of the pipe.

Is foreign 

matter adhering to 

the walls?

Does the

arrow on the tube match the

flow direction?

Refer to the “Alarm Functions” in 
the AXFA11, AXFA14, and AXF 
Integral Flowmeter [Software 
Edition] user manuals.

Perform either of the following:
a. Reinstall the flowtube in 

order to make the arrow and 
flow direction match.

b. Reverse the setting for the 

flow direction.

Change the piping or the 
mounting condition so that 
the tube fills with the fluid.

Remove the foreign matter.

START

Contact a service center.

Check the resistance between 
the flowtube’s A, B, and C 
terminals using a circuit tester.*

1

Is the

resistance between A-C or B-C 

100 M

 or more?

NO

YES

F0521.EPS

*1: Follow the warning in Section 5.7 

before checking. The integral 
flowmeter's resistance cannot be 
checked.
