4.1 General instructions

Make sure that all parts of the instrument exposed to the process, in
particular the sensor element, process seal and process fitting, are
suitable for the existing process conditions. These include above all
the process pressure, process temperature as well as the chemical
properties of the medium.
You can find the specifications in chapter "Technical data" and on the
type label.
In general, LEVEL SWITCH 8112 can be installed in any position. The
instrument only has to be mounted in such a way that the tuning fork is
at the height of the desired switching point.
The tuning fork has lateral markings (notches) that indicate the
switching point with vertical mounting. The switching point refers to
water with the basic setting of the sensitivity switch ≥ 0.7 g/cm³
(0.025 lbs/in³). When mounting LEVEL SWITCH 8112, make sure that
this marking is at the height of the requested switching point. Keep in
mind that the switching point of the instrument is shifted if the medium
has a density other than water - water 1 g/cm³ (0.036 lbs/in³). For
products < 0.7 g/cm³ (0.025 lbs/in³) and > 0.5 g/cm³ (0.018 lbs/in³) the
density switch must be set to ≥ 0.5 g/cm³.
