Siemens SITRANS F Series Operating Instructions Manual page 21

Sensor must be mounted as shown in upper part of figure. Do not mount sensor as shown in
lower part of figure as electrodes then will be positioned at top where air bubbles may occur and
in bottom, where mud, sludge, sand etc. may deposit and cover the electrode, thus impacting
the measurement.
If "Empty Pipe Detection" is used, sensor should be tilted 45° as shown in upper right figure to
maximize full pipe detection and provide accurate volume calculations.
Note
Physical installation of battery pack may influence battery capacity. Optimal battery capacity is
achieved with battery pack in an upright position. Installation examples marked with dotted
cross will affect battery capacity.
Vertical pipes (MAG 8000)
Recommended installation is in a vertical/inclined pipe to minimize wear and deposits in sensor.
Installation in large pipes (MAG 8000)
The water meter can be installed between two reducers (e.g. DIN 28545).
With an 8° reducer, the following pressure drop curve applies. The curves are applicable to
water.
