Capacitive level meters 

CLM-70

 are compact measuring devices consisting of the level meter 

body and a measuring electrode. The level meter body contains measurement electronics 

and a display module. The electronics measure the electrical capacity of the electrode system, 

which is dependent on the level height. The level meter’s electrical output corresponds to the 

capacity (level height) and the measured data are shown on the meter’s display.
The level meter can be adjusted by the display module positioned under the transparent lid. 

The level meter has 4–20 mA current output with HART

®

 communication. The level meter is 

power supplied using a cable connected to the terminal block located under the display and 

adjustment module.

Level meters are available in several measuring electrode modifications (rod and rope-type 

electrodes). Electrodes may be coated with insulation, which is important for their functioning 

in  the  case  of  adherent,  electrically  conductive  and  aggressive  media.  Rod  electrodes  are 

also available in a version provided with a reference tube or a pair of parallel electrodes for 

measuring liquids in non-conductive tanks.

All operations described in this instruction manual have to be carried out by trained 
personnel or by an accredited person only. Warranty and post warranty service must 
be exclusively carried out by the manufacturer.

Improper use, installation or set-up of the sensor can lead to crashes in the ap-
plication.

The manufacturer is not responsible for improper use, loss of work caused by either 
direct or indirect damage, and for expenses incurred at the time of installation or 
during the period of use of the level sensors.

To ensure maximum safety of control processes, we have defined the following safety instruc-

tions and information. Each instruction is labelled with the appropriate pictogram.

Alert, warning, danger

This symbol informs you about particularly important instructions for installation and 

operation of equipment or dangerous situations that may occur during the installation 

and operation. Not observing these instructions may cause disturbance, damage or de

-

struction of equipment or may cause injury.
