Notice
Short-time overload operation of 20% above the maximum flow rate Qmax is
permissible. Such load conditions should be avoided, however, since in
most cases they cannot be controlled and exceed the officially approved
limits for custody transfer metering. Moreover, such overloads reduce the
service life of the gas meter.
Warning
The gas flow must be free of foreign particles, dust or liquids. Otherwise it is
recommended that filters or separators be installed.
Danger
With the start-up of this device it is to be observed that all cables were correctly
laid and connected.
The housing must be completely closed.
With the connection and the start-up of the encoder, observe the guidelines of
the appropriate norms
DIN EN 60079-0 and
DIN EN 60079-14
