flow. The error resulting from this assumption (typically 1 to 5 %) is often considerably
smaller than the error caused by inaccurate composition data. This method should not be
used for condensing gases (e. g. saturated steam).

conditions.
10.8.4 Calculation of the measured variables
A flow computer can be found in the electronics of the measuring device with order code
for "Sensor version", option "mass (integrated temperature measurement)" and option "mass
(integrated pressure/temperature measurement)". This computer can calculate the
following secondary measured variables directly from the primary measured variables
recorded using the pressure value (entered or external) and/or temperature value
(measured or entered).
