Safety instructions for operation
During operation with hot fluids, contact with the surface may result in burns.
Aggressive fluids may result in corrosion or abrasion of the parts that come into contact with the
medium. As a result, pressurized fluids may escape prematurely.
Wear to the flange gasket or process connection gaskets (e.g., aseptic threaded pipe
connections, Tri-Clamp, etc.) may enable a pressurized medium to escape.
When using internal flat gaskets, these can become embrittled through CIP/SIP processes.
If pressure shocks exceeding the device's permissible nominal pressure occur continuously
during operation, this can have a detrimental effect on the device's service life.
1.10 Technical limit values
The device is designed for use exclusively within the stated values on the name plate and within
the technical limit values specified in the data sheets.
The following technical limit values must be observed:
•
The permissible operating pressure (PS) in the permissible temperature (TS) may not
exceed the pressure-temperature ratings.
•
The maximum operating temperature may not be exceeded.
•
The permitted operating temperature may not be exceeded.
•
The housing protection system must be observed.
•
The flowmeter sensor may not be operated in the vicinity of powerful electromagnetic fields,
e.g., motors, pumps, transformers, etc. A minimum spacing of approx. 1 m (3.28 ft) should
be maintained. For installation on or to steel parts (e.g., steel brackets), a minimum spacing
of approx. 100 mm (3.94 inch) should be maintained (based on IEC801-2 and IECTC77B).
1.11 Allowed Fluids
When measuring fluids, the following points must be observed:
•
Fluids may only be used if, based on state-of-the-art technology or the operating experience
of the user, it is assured that chemical and physical properties of the components coming
into contact with the fluids (signal electrodes, ground electrodes, liners and, possibly,
process connections, protective plates or protective flanges) are not affected during the
operating life.
Fluids with unknown properties or abrasive fluids may only be used if the operator can
•
perform regular and suitable tests to ensure the safe condition of the device.
Observe the information on the name plate.
