Instructions Acc. To Directive 97/23/Ec, Pressure Devices - ABB FMT200-D Operating Instruction

2.2.3
2.2.3.1 General
• The thermal mass flowmeters FMT200-D and the pipe components:
– partial measuring section with external threads
– partial measuring section with flanges
– weld-on adapter
are part of the pipeline. A rating of the entire system according to PED is to be carried out by the approved
regulatory agency on the customer side.
• The "FMT200-D" measuring systems are intended to be used for flow measurement of gaseous
media, only.
• The device may be used for the specific application and under the conditions specified in the order confirma-
tion, only. Otherwise, the device may be impaired, damaged or even destroyed.
• Only those media (fluids) may be measured which – according to the state of the art or the operator's experi-
ence – do not affect the chemical or physical material properties of process-wetted parts that are essential for
operational reliability.
• The device must be included in the routine maintenance procedure of the plant and checked accordingly.
• The used materials must be checked by the user for compatibility with the respective application.
• The max. temperature and pressure specified on the rating plate must not be exceeded.
• Prior to mounting or dismounting the pipe components or transducers always make sure that the pipe is fully
depressurized.
• Prior to starting any installation work on pipes with aggressive, toxic, irritant or noxious substances always
rinse the pipes carefully. When working on the pipes observe the applicable regulations for the prevention of
accidents.
• Do not use damaged pipe components or transducers. Such units must be withdrawn immediately and re-
turned to the vendor for repair.
• Dismounted pipe components or transducers that have been in contact with aggressive, toxic, irritant or nox-
ious substances must be cleaned thoroughly and wrapped and marked accordingly when they are returned to
the vendor.
• If a leakage should occur at a measuring point, the respective point must be put out of service.
• Immediately replace defective gaskets or O-ring seals. Do not re-use.
• Mechanically marking or making alterations to pipe components or sensors can lead to damage to the
components and is thus prohibited. For weld-on adapters, cutting to length and welding on to the pipe are per-
mitted.
