2.5 Concentration offset
In both concentration modes, the MFC 300 and MFC 400 allows the user to set a concentration
offset. An offset may be needed where: a) there is a difference between the value measured by
the massflow meter and measurements taken in a laboratory, b) the process data does not fit
well with the converter's algorithms, or c) where there are differences between the standard
Brix values and the customer’s concentration. A good example is where pure water is not the
carrier fluid, allowing for the use of additives, fruit juices etc.The offset can be up to ±100% and
up to three decimal places, for fine corrections.
Setting the offset Setting the offset Setting the offset Setting the offset
To set the concentration offset, use menu option: C2.2.2 Conc. Offset or C2.3.2 Conc. Offset and
enter the required offset value. For example, if the meter’s concentration value is 1% too low,
enter the value of +001.000 %.This will add 1% to the calculated concentration value.
