Installation Liquiphant FTL51B
12 Endress+Hauser
5.1.2 Take viscosity into consideration
Low viscosity
> 25 (0.98)
D
A0033297
 8 Installation example for low-viscosity liquids. Unit of measurement mm (in)
D Diameter of installation socket: at least 50 mm (2.0 in)
Low viscosity, e. g. water: < 2 000 mPa⋅s
It is permitted to position the tuning fork within the installation socket.
High viscosity
> 40 (1.57)
A0037348
 9 Installation example for a highly viscous liquid. Unit of measurement mm (in)
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!
