D184B123U04 Variable area flowmeter

Possible risks present during transport

the center of gravity may not be in the center of the equipment
any attachment points and
transport protection (e.g. sealing of openings)

Possible risks present during assembly

the flow direction corresponds to the marking.
the instrument is installed on a stress free manner (e.g. parallel mating flanges) and is only installed
with the specified seals.
the piping in front of and behind the equipment is properly supported (refer to information in main
operating manual).

Possible risks during electrical installation

Only specialists may connect the equipment up to the electric circuit in accordance with the electrical
diagrams.
Ground the flowmeter.

Possible risks when used in Ex areas

Possible risks during active operation

Operations with abrasive fluids and/or cavitation may damage pressure containing parts.
During the flow of hot media, contact with the surface may result in burns.
Aggressive fluids may result in corrosion and abrasion. Pressurised fluids might escape prematurely.

Possible risks during servicing and maintenance

Before working on the instrument (removing/opening), ensure that the instrument and if necessary
adjacent lines or tanks are depressurised.
Only for model D10A32XX: Before opening the equipment, check whether hazardous substances
were used as the flow medium. There may be hazardous residue in the equipment and this may
escape upon opening.
If piping vibrations are present, we recommend securing the flange bolts and nuts to prevent them
from loosening.
Included in the responsibilities of the system operator are periodic inspections, to check:
– the operation
– the seals
– the wear (corrosion, abrasion, cavitation)
