5.1 Mounting preparation
To protect the instrument from mechanical damage keep it in the
„
outer carton until installation.
EN
The measuring instrument should only be removed from the
„
packaging shortly before mounting at the measuring point.
With CIP (cleaning in place) it is recommended to clean the
„
measuring instrument again after mounting, using the established
process of the operator.
With COP (cleaning out of place) it is recommended to clean the
„
measuring instrument again before mounting, using the estab-
lished process of the operator.
On removal from the packaging, and during mounting, particular
„
care must be taken to avoid damage and any mechanical defor-
mation to the diaphragm.
Check the zero point. In case of a zero offset, carry out a zero
„
point setting. See chapter 5.7 "External zero point setting".
5.2 Installation
Do not damage the diaphragm; scratches on the diaphragm (e.g.
„
from sharp-edged objects) are the main causes of corrosion.
For sealing, choose appropriate seals.
„
For flange mounting, only use sealings with a sufficiently large
„
inner diameter and centre them; contact with the diaphragm leads
to measuring errors.
When using soft or PTFE sealings, observe the instructions of the
„
sealing manufacturer, particularly with regard to tightening torque
and load cycles.
