Models designed for hazardous areas with ATEX / IECEx approval
Models
Approvals
VT41 / ST41 / VR41 / SR41 • Operation in Zone 1:
Ex ib IIC (intrinsically safe supply)
• Operation in Zone 2:
Ex nA [nL] IIC (non-intrinsically safe supply)
• Operation in Zone 21 / 22:
Ex tD A21 / Ex tD A22 (non-intrinsically safe supply or
intrinsically safe supply)
Important
All types of protection are noted on the name plate.
Flowmeters operating in Category 3 (Zone 2 / 22) may subsequently be operated in Category
2 (Zone 1 / 21) without modification.
The respective applicable maximum values must be complied with.

Approvals
VT42 / ST42 / VR42 / SR42 • Operation in Zone 1:
Ex d [ib] IIC (non-intrinsically safe supply)
• Operation in Zone 1:
Ex ib IIC (intrinsically safe supply)
• Operation in Zone 2:
Ex nA [nL] IIC (non-intrinsically safe supply)
• Operation in Zone 21 / 22:
Ex tD A21 / Ex tD A22 (non-intrinsically safe supply or
intrinsically safe supply)
Important
All types of protection are noted on the name plate. In the case of operation in Zone 1, the
user specifies the type of protection by means of the type of supply.
Flowmeters operated in Category 3 (Zone 2) may subsequently be operated in Category 2
(Zone 1) without modification. Within Category 2, the Ex d [ib] design may subsequently be
operated as EX ib without modification.
The respective applicable maximum values must be complied with. The significant differences
between models are listed in the table titled "Differences between explosion-proof designs with
regard to safety engineering". Detailed descriptions appear later in this section.
