1.4 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 pressure (PS) in the permissible fluid temperature (TS) may not exceed the
pressure-temperature ratings.
• The maximum operating temperature may not be exceeded.
• The permitted ambient temperature may not be exceeded.
• The housing protection class must be observed.
• The flowmeter primary may not be operated in the vicinity of powerful electromagnetic fields,
e.g., motors, pumps, transformers, etc. A minimum spacing of approx. 100 cm should be
maintained. For installation on or to steel parts (e.g., steel brackets), a minimum spacing of
approx. 100 mm 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 agents 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.
1.6 Operator liability
• Before the use of corrosive and abrasive materials to be measured, the operator must clarify
the resistance of all parts that come into contact with the materials to be measured. ABB will
gladly support you with the selection, however, cannot accept any liability.
• The operators must strictly observe the applicable national regulations in their countries with
regards to installation, function tests, repairs, and maintenance of electrical devices.
1.7 Personnel qualification
The installation, commissioning and maintenance of the device may only be carried out through
trained specialist personell authorized by the plant operator. The specialist personnel must have
read and understood the manual and comply with its instructions.
