4.3 Orientation of Kamstrup’s flow sensors
The recommended orientation of the flow sensor in an installation takes into account the metrological sensitivity of
the flow sensor to orientation, for example because of orientation-dependent flow profiles; poor water quality of
district heating water, e.g. dirt, which can accumulate in the flow sensor; air in the system and finally because of
environmental requirements, for example in case of condensation. The recommendations may vary for each of the
types because of their diversity in the design.
4.3.1 General recommendations
Kamstrup’s flow sensors can be
mounted vertically, horizontally or at
an angle.
If Kamstrup flow sensors are vertically
mounted, they can be turned ±360°
around the pipe axis.
The plastic box should be placed on
the side (at horizontal mounting). See
below for additional details.
Figure 3. Separate mounting of Kamstrup flow sensors. Vertically, horizontally or at an angle.
At horizontal mounting, Kamstrup’s flow sensors can be turned around the pipe axis. Acceptable angles of rotation
for the various types of Kamstrup flow sensors can be seen Figure 4 and Figure 5.
At medium temperatures above 90 °C and below ambient temperature, i.e. for cooling applications, calculator and
Pulse Transmitter/Pulse Divider must not be mounted on the flow sensor. Instead wall-mounting is recommended.
The orientation of the flow sensor in a cooling application does therefore not need to take the readability of the
calculators display into account and can thereby be limited to the optimum orientation of the flow sensor only.
