Take viscosity into consideration

Low viscosity
Low viscosity, e.g. water: < 2 000 mPa⋅s
It is permitted to position the tuning fork within the installation socket.
 5 Installation example for low-viscosity liquids. Unit of measurement mm (in)
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!
