Introduction to the universal index
This is the standard version and it has two 8-digit mechanical roller
indexes. Depending on the flow direction, one index will be covered.
The index can be rotated in any position, so that the meter can be
used in any position. Two separate LF pulse signals can be
monitored by a integrated male binder connection in the index.
Introduction to the basic index
Optional is the basic index. This is a simplified version of the universal
index. It is suitable for only one flow direction. It is equipped with a
male binder to monitor the LF pulses.
Introduction to the instrument drive
This is a standalone unit to provide a mechanical input into for
example a volume corrector. To rotate the instrument drive, see
instructions below.
Rotating the index
To rotate the Universal index or the instrument drive it is required to remove the two M5 screws.
Therefore the service sealing will have to be removed. After the index has been rotated in the correct
position, the two M5 screws should be mounted and the service sealing will have to be applied again.
(Note: The position of the M5 screws may vary due to customer standards.)
The basic index can always be rotated in the desired position.
