5.3 Set the installation length
A = response level
H = tank height
SH = height of the connection piece
L = probe length
L1 = installation length
L2 = extension length
L3 = mounting length (at least 60 mm)
MET = maximum installation depth (= active zone; 31 mm)
► Select the installation length L1 so that at least half the MET zone is covered
when the response level A has been reached, that is:
L1 = (H - A) + ½ MET + SH
The unit switches when the level reaches the MET zone The exact position
(exact response level) depends on the following factors:
• characteristics of the medium
• installation conditions
• adjustment of the unit (→ chapter 8 Settings).
