1 Safety instructions for repair work
ABB flowmeters are designed to be easy to repair thanks to
uniform replacement parts and simple replacement of
predefined parts.
However, if repair work is not carried out in accordance with the
guidelines, this may result in malfunctioning of the device,
causing serious injury to persons, and harm to the environment.
This is especially true for safety-critical devices and those
certified for use in explosion hazard environments.
Certifications will also lapse if the repairs were not carried out
with the proper tool or by persons without adequate training.
We therefore recommend all repair work on flowmeters be
carried out by ABB service technicians.
As the manufacturer of the device, ABB cannot guarantee the
necessary quality of the repair procedures if the work and/or
parts exchange was not carried out by ABB.
The plant operator is responsible for all repairs carried out by
the customer, plant operator, or third party. In this case, ABB will
reject all responsibility for any improper device functionality, in
particular all safety-related functions.
ABB does not assume any liability for the deterioration or loss of
device performance, malfunctions, or damage arising from the
above repair work or replacement. All liability for defects shall
lapse when the replacement or repair work is not carried out by
ABB. If you are unsure about the repair process even if some or all
replacement parts are available, please get in touch with ABB
Service before beginning work.
Respect national and internal laws when carrying out repairs. In
particular laws relating to certified flowmeters used in explosion
hazard environments. Repair work which is carried out without
following the legal requirements can result in the revocation of
your operating permit.
