General instructions
Note:
For safety reasons, the instrument must only be operated within the
permissible process conditions. You can find detailed information on
the process conditions in chapter " Technical data" of the operating
instructions or on the type label.
Hence make sure before mounting that all parts of the instrument ex-
posed to the process are suitable for the existing process conditions.
These are mainly:
•
Active measuring component
•
Process fitting
•
Process seal
Process conditions in particular are:
•
Process pressure
•
Process temperature
•
Chemical properties of the medium
•
Abrasion and mechanical influences
The instrument is suitable for standard and extended ambient condi-
tions acc. to DIN/EN/IEC/ANSI/ISA/UL/CSA 61010-1. It can be used
indoors as well as outdoors.
In general, SITRANS LVL100 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.
Keep in mind that the swichting point can vary dependent on the
installation position.
The switching point refers to the medium water (1 g/cm³/0.036 lbs/
in³). Please keep in mind that the switching point of the instrument
shifts when the medium has a density differing from water.
