BASIC INFORMATION
• Level meters with coated electrode have protection cover at the end of electrode, which is
necessary take down before mounting.
• Level meters mount in vertical position to upper lid of tank or reservoir by welding flange, fixing
nut or Clamp flange.
• For mounting level meter to the metal tank or hopper, it is not necessary to ground the housing
again.
• In case of installation in concrete sumps or silos, it is appropriate to install the level meter onto
a metallic auxiliary construction (console, lid, etc.) and then connect with metal constantly
submerged object, eventually with steel armouring.
• For level measurement of material in plastic and glass vessels by level meter without reference
tube is necessary to connect grounding screw at housing with auxiliary electrode which is
fixed in an appropriate manner to the outer casing of vessels (or at the inner wall). Material
of auxiliary electrode must be selected with consideration for the working environment and
properties of measured material.
VARIANTS WITH ROD ELECTRODE
For types : DLM-35_-20, 21, 22, 25, 30, 31
E
- the length of electrode [mm]
- select so that the end of the
electrode is dipped min. 20 mm
below the lowest measured level
h
- the distance from the
bottom - min. 20 mm
a
- the distance from the wall -
min. approx. E/20
d
- the diameter of auxiliary
tube vessel - min. 40 + E/20
(smaller dimension has to be
discussed with producer)
auxiliary electrode
width = min. 30 mm
(necessary only for non-
metal vessels)
