Take switch point into consideration
The following are typical switch points, depending on the orientation of the point level
switch.
Water +23 °C (+73 °F)
Minimum distance between the fork tip and the tank wall or pipe wall:
10 mm (0.39 in)
~13 (0.5)
~5 (0.2)
~12.5 (0.49)

Take viscosity into consideration
Viscosity values
• Low viscosity : < 2
000 mPa⋅s
• High viscosity: > 2
000 to 10
000 mPa⋅s
Low viscosity
Low viscosity, e.g. water: < 2
000 mPa⋅s
It is permitted to position the tuning fork within the installation socket.

High viscosity
NOTICE
Highly viscous liquids may cause switching delays.
‣
Make sure that the liquid can run off the tuning fork easily.
‣
Deburr the socket surface.
High viscosity, e.g. viscous oils: ≤ 10
000 mPa⋅s
The tuning fork must be located outside the installation socket!
