6.0 MAINTENANCE
6.1 General
Except for an occasional performance verification check, there is no required routine maintenance
for the flowmeter. In the event that the flowmeter body must be replaced, the company offers a
repair/exchange program to facilitate replacement of a defective meter or converter.
If the equipment is beyond the warranty limit, under this programa fixed-price will be charged for the
replacement of the defective equipment with appropriate credit issued when the repairable unit is
received by the factory (charges prepaid).
All flowmeters and/or signal converters being returned to ABB for repair
must be free of any hazardous materials (acids, alkalis, solvents, etc.). A
Material Safety Data Sheet (MSDS) for all process liquids must
accompany returned equipment. Contact the company for authorization
When communicating with the company regarding replacement of a complete meter, it is important to
reference the complete instrument serial number to assure that the correct replacement will be
supplied. The serial number is referenced on the manufacturing specification sheet supplied with the
flowmeter and on the instrument data tag.
Operation and maintenance procedures for the signal converter are pro-
vided in the instruction manual supplied with the signal converter.
6.2 System Troubleshooting
If the flowmeter appears not to be operating properly, the following procedure can be used as a guide
to isolate the malfunctioning device to either the flowmeter or the signal converter. A standard
multimeter and an oscilloscope are suitable for making the test measurements.
ELECTRICAL SHOCK HAZARD. Equipment powered by an ac line
voltage presents a potential electric shock hazard. Servicing of the
magnetic flowmeter or signal converter should only be attempted by a
Some of the surface-mounted IC devices used in the signal converter
are static sensitive and may be damaged by improper handling. When
adjusting or servicing the signal converter, use of a grounded wrist
strap is recommended to prevent inadvertant damage to the integral
