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 steel welding
flange ON-36x2 (steel 11375), stainless steel welding flange NN-36x2 (stainless steel 1.4301),
fixing nut UM-36x2 (stainless steel 1.4301) or Clamp flange.
For mounting level meter to the metal tank or reservoir is not necessary to ground housing
again.
In case of installation in concrete sumps or silos it is properly to install level meter at metallic
auxiliary construction (console, lid, etc.) and then connect with metal all the time submerged object,
eventually with steel armouring.
For measuring 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 by the
appropriate method to the outer casing of vessels (or at inner wall). Material of auxiliary
electrode
is necessary to choose with consideration to the working environment and properties of measured
material.

METAL AND NON-METAL VESSESLS
E
- the length of electrode
[mm] - the end of the electrode
has to be dipped min. 20 mm
below the lowest measured level
h
- the distance from the
bottom - min. 50 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)
