The design of the sensor MAG 1100 allows for
bi-directional flow. Dimension L is given in the
previous table.
The arrow at the sensor indicates recommended
flow direction (the meter has been calibrated
with flow in arrow direction "+").
Installation
Tightening
The bolts must be tightened using up to 50% of the max.
tightening torque for the pipe dimensions stated. The max.
tightening torque for different size pipes is given in the table
d
.
The bolts must now be cross-tightened in the sequence shown
in
c
, using up to 100% torque.
First place three stay-bolts to locate the sensor, see
a.
These should be tightened gently, making
sure that each gasket fits exactly into its recess at either end of the sensor, see
b.
The remaining flange bolts can now be inserted and tightened using about 25% of the actual
tightening torque, see table d.
Installation of the cover or
transmitter on the termi-
nal box
1.
Mount the cover or the transmitter on the
terminal box.

. It is important that the screws are firmly
tightened (4 Nm). Use a large screwdriver
fitting into the screw slot.
