- It is possible to apply screening and to run a cable to the meter housing or
the pipe. Make sure to check in advance that the earthing system used allows
earthing on both sides (earth loops and potential difference in earthing).
- The assignment of the lower two terminals in the connection box of the encoder
index determines the direction of gas flow:
Bridge on lower terminals (as delivered): Upper index is activated
Flow direction: from bottom to top or from right to left.
Lower terminals unassigned: Lower index is activated
Flow direction: from left to right or from top to bottom.
A pulse generator (Type LF) may be connected for pulse output to external devices
(e.g. a volume corrector). Fit the pulse generator (if required) as described above
in section 12.
