5.1.3 Viscosity
Switching delays may occur in the case of highly viscous liquids. Ensure that the liquid can
easily run off the tuning fork:
• If installing in vessels with high-viscosity liquids (A), the tuning fork may not be located in
the installation socket!
• If installing in vessels with low-viscosity liquids (B), the tuning fork may be located in the
installation socket!
• The installation nozzle must be no less than the minimum diameter of 50 mm (2.0 in).
