1.4 Personnel for Installation, Start-up and Operation
•
Mounting, electrical installation, start-up and maintenance of the instrument may
only be carried out by trained personnel authorised by the operator of the facility.
Personnel must absolutely and without fail read and understand this Operating
Manual before carrying out its instructions.
•
The instrument may only be operated by personnel who are authorised and trained
by the operator of the facility. All instructions in this manual are to be observed
without fail.
•
In case of corrosive fluids, the compatibility of the material of all wetted parts such
as measuring pipe, bluff body, sensor and gaskets is to be verified. This also ap-
plies to fluids used to clean the Prowirl 77 flowmeter. Hauser will be
pleased to provide you with any help required.

The installer has to make sure that the measuring system is correctly wired up
according to the wiring diagrams. The complete bus system is to be grounded.
Please observe all provisions valid for your country pertaining to opening and repair
of electrical devices.
1.5 Repairs, Dangerous Chemicals
The following procedures must be carried out before a Prowirl 77 is sent to
Hauser for repair:
•
A note must be enclosed with the instrument, containing a description of the fault,
the application and the chemical and physical properties of the fluid being
measured.
•
Remove all residue which may be present. Pay special attention to the gasket
grooves and crevices where fluid may be present. This is especially important if the
fluid is dangerous to health, e.g. corrosive, poisonous, carcinogenic, radioactive,
etc.
•
No instrument should be returned to us without all dangerous material being
removed first.
Incomplete cleaning of the instrument may result in waste disposal requirements or
cause harm to personnel (burns, etc.). Any costs arising from this will be charged to
the operator of the instrument.
