1.3 Function
The volume corrector ERZ2000-NG is designed to operate various sensors, particu-
larly flow rate and gas analysis sensors, evaluate their signals or adopt and deter-
mine resulting operating and nominal volume flows. The resulting billing variables can
be represented in a graph and checked via alarm output, etc. The ERZ2000-NG cor-
responds to the standards, directives and specifications listed in
chapter 1.5 Areas of
application
.
Figure
1 explains the functional principle.
Figure 1: Functional principle
It is important that the ERZ2000-NG both adopts "finished" values (e.g. pressure,
temperature, etc.) from the sensors and can, in part, processes "raw signals" of the
individual sensors and then recalculate them (e.g. the pressures at the orifice flow
meter are converted to a volume flow, etc.).
