Technical Limit Values; Allowed Fluids - ABB FSM4000 Series Commissioning Instruction

1.4

Technical limit values

The device is designed for use exclusively within the stated values on the model 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).
1.5

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.
