5.1 Start-up
Start-up may only initiate when the vortex flowmeter:
•
is correctly installed in the system and connected.
•
has been checked for the proper state with regard to its installation and connection
requirements.
•
has been correctly locked to the electronics and terminal compartment.
The user of the system must have it checked before start-up in compliance with the national
regulations for checks before start-up.
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.
Opening the signal converter (protection type "flameproof enclosure" or "dustproof housing" or
"terminal compartment in increased safety") in hazardous areas is only permitted in a de-
energised state.
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.
