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 fitting, are suitable for the existing process conditions, such

as 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

nameplate.

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.
