The hydrostatic level meter HLM–35
is a compact measuring device containing a ceramic
or stainless steel strain gauge sensor and evaluation electronics in a stainless steel probe.
The ceramic sensor is resistant to different against various liquids (water, oil, coolants, water
solutions, etc.). The probe is produced in a configuration with a valve or a capillary, which
serves to deliver atmospheric pressure to the probe. The front side of the probe is open,
which makes the level meter more resistant against adhesion of coarser soiling. The level
meter does not include any elements that can be set. LED signal function.

description
All the operations described in these operating instructions must be made only
by trained personnel or by an authorised person. Warranty and post-warranty
repairs must be carried out exclusively at the manufacturer. Incorrect sensor
use, assembly or configuration may cause accidents in the application (tank
overfilling or damage to the system components).
The manufacturer is not responsible for the improper use, working losses in-
curred by either direct or indirect damage and the expenditure incurred during
the installation or the use of the sensor.
In order to ensure maximum safety of control processes, we have defined the following safety and
information instructions. Each instruction is marked with a corresponding pictogram.

application
For continuous level measurement of clean, lightly soiled or turbid water in non-pressure
vessels. Further for various liquids (oil, coolants, etc.). If the level meter is used on a liquid
other than water, it is necessary to make correction of output current (resp. voltage) accord
