The ERZ2000-NG has different totalizer sets which can fulfill different tasks, e.g.:
x
Some gas flow meters can determine volume flow forwards and backwards
with the same accuracy. Then, the totalizer can be used in forward and back-
ward operation:
o
Filling and emptying of a gas accumulator
o
With changeover of lines of different pressures
(e.g. changeover of a line with low pressure to a line with higher pres-
sure), temporary return flow can arise.
x
The flow rate is determined in different lines.
o
There is a
–
mostly larger
–
line with corresponding gas totalizer for win-
ter operation and an additional
–
usually smaller
–
line with some gas
totalizer for summer operation.
o
Gas from different sources / providers is supplied to the downstream
network.
