7 . Mechanical mounting
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.
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)
