Flow Measurement - Siemens SITRANS P DS III Operating Instructions Manual

● Create an assignment between the measured mass value and the output value by setting
these parameters:

You can also adjust the output to another process value. Assign the required unit to the
parameters under the rubric output scaling. Assign the start of scale and full scale values
according to the measured value scaling.
