1.1.9
Note the following before transporting equipment to the measurement site:
•
•
1.1.10
During assembly, ensure that:
•
•
•
•
•
1.1.11
Only specialists may connect the equipment up to the electric circuit in accordance with the electrical di-
agrams.
Attention!
!
When the housing cover is open, EMC and contact protection is no longer provided.
Earth the flow measurement system.
Observe max. signal values for signal inputs and outputs of measurement recorder.
1.1.12
Warning!
STOP
The equipment is not authorised for use in hazardous areas and must therefore not be installed and op-
erated in such areas.
1.1.13

1.1.14
Before disassembling the equipment, depressurise the equipment and if necessary any neighbouring
lines or containers. Otherwise, pressurised fluids may spray out when the process connection is loosened
and cause serious injury.
Before opening the equipment and/or before disassembly, check whether hazardous materials have
been used as the flow fluids. There may be hazardous residue in the equipment and this may escape
upon opening. The process connection should be secured so that it cannot come loose as a result of pip-
ing vibrations. Depending on the application, the process connection seals should be checked periodical-
ly and replaced if necessary.

Possible risks present during transport

The centre of gravity may not be in the centre of the equipment.
Ensure that the threaded connection and angle connector are not damaged.

Possible risks present during assembly

The flow direction corresponds to the marking.
The maximum tightening torque of the process connection thread is not exceeded. (see Page
GB 13)
The equipment is fitted without mechanical stress (torsion, bending) and is only fitted with appropri-
ate gaskets.
Check the suitability of the Viton gaskets used at the face end for your intended operating conditions
The equipment displays should be aligned to the user wherever possible.

Possible risks during electrical installation

Possible risks when using in hazardous areas

Possible risks during active operation

During the flow of hot fluids, contact with the surface may result in burns.
Aggressive fluids may result in corrosion, abrasion and cavitation on liner or electrodes and pres-
surised fluids may thereby escape prematurely.
Pressurised fluids may escape as a result of fatigue / brittleness of process connection seals.
Overtorqueing of the male thread process connection may result in damage of the meter tube. Pres-
surised fluids may thereby escape prematurely.
