Appendix
Ex-Safety Instruction for the operating manuals
Description:
The Rheonik Coriolis massflow meter system RHM/RHE has been designed and manufac-
tured according to ATEX 94/9/EC directive with reference to EN60079-0:2006, EN60079-
1:2007, EN60079-7:2007, EN60079-11:2007, EN60079-26:2007 standards.
The measurement system is a flow-sensor RHM, connected by a multiconductor cable to
the remote electronic unit RHE. Depending on the type the remote also can be mounted
inside the hazardous area (see table – installation location).

Marking:
The instrument marking comprises two parts:
1.
The
specific marking
, which indicates for which ignitable atmospheres the instru-
ment, will be suitable, for which hazardous area installation locations, depending
on the degree of protection, and who is the notified body, involved in the produc-
tion control stage.
2.
The
additional marking
gives necessary information essential for safe use. This
supplementary marking is according to the European standard series
EN60079-0:2006 for electrical products for potentially explosive atmospheres.
