4.1 General instructions
Make sure that all parts of the instrument coming in direct contact
with the process, especially the sensor element, process seal and
processtting,aresuitablefortheexistingprocessconditions,such
as process pressure, process temperature as well as the chemical
properties of the medium.
Youcanndthespecicationsinchapter"Technical data" and on the
nameplate.
The instrument is suitable for standard and extended ambient condi-
tions acc. to DIN/EN/IEC/ANSI/ISA/UL/CSA 61010-1.
In general, SITRANS LVL200E 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 applies
to water in conjunction with the basic setting of the density switch
≥0.7g/cm³(0.025lbs/in³).WhenmountingSITRANSLVL200E,
make sure that this marking is at the height of the requested switch-
ing point. Keep in mind that the switching point of the instrument will
shiftifthemediumhasadensityotherthanwater-wateris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.
Keepinmindthatfoamswithadensity≥0.45g/cm³(0.016lbs/in³)
are detected by the sensor. This can lead to erroneous switchings,
particulary when the sensor is used for dry run protection.
