Actuator out
- Read parameter 55 – Actuator Out
(Actuator in %)
Density (Coriolis)
- Read parameter 270 – Actual Density
(Density in kg/m
3
)
External Master Flow (ratio dosing)
- Read parameter 11 – Analog Input
(analog input of slave =
measure of master)
Parameter is without flow unit and is depending on the configuration of the input signal.
Commonly used is Signal 4 – 20 mA = Value 0 – 32000 = Flow 0 – 100%
Counter information (batch dosing)
- Read parameter 122 – Counter Value
(Counter during dose)
- Read parameter 128 – Counter Unit
(Flow measurement unit)
- Read parameter 28 – Alarm Info
(Value 16, Counter Limit
Batch size reached)
