The capacitative level meters DLM

®

 are intended for continuous level measurement of liquid 

and bulk solids in tanks, vessels, sumps or silos, hoppers etc. They are comprised of a housing 

with electronic module and measuring electrodes. The electronic part converts the size of the 

capacity to the current signal (4 ... 20 mA) or voltage signal (0 ... 10 V).Level meters are made 

in several modifications of measuring electrodes (rod and rope). The electrodes can be covered 

by  an  insulating  coating  in  case  level  measurement  of  adhesive,  aggressive  or  electrically 

conductive media. Rod electrodes are also available in a version with reference (coaxial) tube for 

level measurement of liquids in tanks made from non-conductive material.
Level  meters  are  produced  in  the  following  performances: 

N

  –  for  non-explosive  areas,  

NT

 – high temperature for non-explosive areas, 

Xi

 – Explosion proof – intrinsically safe for hazard-

ous (explosive) areas and 

XiM

 – Explosion proof – intrinsically safe for use in mines with methane 

or flammable dust presence danger (see technical specifications). There are high temperature per-

NT, XiT, XiMT

 available. DLM are offered in variants with various types of process con-

nection (metric and pipe thread, pressure thread NPT).

Safety

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 application. 
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.
