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.
