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" or on the

type label.

In general, SITRANS LVL200E can be installed in any position. The

instrument simply 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 SITRANS LVL200E, 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.

Keep in mind that foams with a density > 0.45 g/cm³ (0.016 lbs/in³) are

detected by the sensor. This can cause faulty switchings particulary

when used as dry run protection system.
