Orientation of the sensor
Flow direction
The calibrated flow direction is indicated by the arrow on the sensor. Flow in this direction will
be indicated as positive by default. The sensitivity and the accuracy of the sensor do not change
with reverse flow.
The indicated flow direction (positive/negative) is configurable.
CAUTION
Accurate measurement
The sensor must always be completely filled with process media in order to measure accurately.
Orienting the sensor
The sensor operates in any orientation. The optimal orientation depends on the process fluid
and the process conditions. Siemens recommends orienting the sensor in one of the following
ways:
