Advanced functions
▪ one-stage mode with single valve
▪ two-stage mode to control two valves for accurate filling
Without using an external flow computer, data related to the process can be transmitted
via communication protocol. The error management function allows the user to set alarms
and warnings accordingly the application needs.

20.4 Viscosity function
The Viscosity function allows the user to have an estimation of the viscosity of the fluid.
The function can be used as redundant viscosity control or as reference value to activate
other processes like for instance fluid heating systems.
The viscosity estimation is calculated based on a comparison between measured
pressure loss Δp and a "calculated" Δp
meter (refer to related instruction manual for the correct installation).
