5.1 Start-up
Start-up is only permitted when the measuring device:
• is correctly installed in the system and connected.
• has been checked for the proper state with regard to its installation and connection
requirements.
The operator of the system has to check prior to start-up, if the start-up was in compliance with
the national regulations for checks.
5.2 Operation
Vortex flowmeters must be operated in such a way that they remain within the maximum and
minimum permissible temperatures and pressures and the electrical limit values.
Vortex flowmeters may only be operated if the equipment parts necessary for safety are effective
in the long run, and are not rendered inoperable during operation.
In case of operation with flammable products the measuring units must be included in the
periodic pressure tests of the system.
Operating the converter insert during operation is permitted. To do so, remove the housing
cover. Close the housing cover immediately after adjustment of the converter insert.
Terminal compartments (protection type "intrinsic safety") may be opened even in an energised
state in hazardous area.
Work on electrical connections (e.g. configuration via the HART
an energised state. Terminal compartments must be closed immediately upon completion of the
work.
5.3 Electrostatic charge
In order to avoid ignition hazards due to electrostatic charge, vortex flowmeters may
not be used in areas with:
• processes that generate strong charges,
• mechanical friction and cutting processes,
• spraying of electrons (e.g. in the vicinity of electrostatic painting systems) or
• pneumatically conveyed dust is exposed.
CAUTION!
Electrostatic charging of the housing surface by friction must be avoided.
The devices must not be dry cleaned.
