Notwithstanding the foregoing, the installation suggested below permits installation in an open
down pipe. Pipe restrictions or the use of an orifice plate with a smaller cross-section than the
nominal diameter prevent the pipe from running empty while measurement is in progress.

3.2.4 Orientation
Vertical
Recommended orientation with upward direction of flow (View A). With this orientation, entrained
solids will sink and gases will rise away from the sensor when the fluid is stagnant. The piping can
be completely drained and protected against solids buildup.
Horizontal
In the recommended installation range in a horizontal installation position (View B), gas and air
collections at the pipe cover and problematic deposits at the bottom of the pipe have a smaller
influence on measurement.

3.2.5 Inlet and outlet runs
If possible, install the sensor well clear of assemblies such as valves, T-pieces, elbows, etc. The
longest inlet and outlet run must be taken into consideration if two or more flow obstructions are
present. The following inlet and outlet runs are recommended to comply with measuring accuracy
specifications:

3.2.7 Foundations, supports
For all nominal diameters, mount the sensor on a foundation of adequate load-bearing strength.
A0008751
Fig. 12: Correct support for large nominal diameters
3.2.8 Adapters
The sensor can also be installed in a pipe with a larger nominal diameter using appropriate adapters
in accordance with (E) DIN EN 545 (double-flange adapters). The resulting increase in flow velocity
improves accuracy if the fluid flows very slowly.
The chart below can be used to determine the drop in pressure caused by reducers and expanders:
"Caution!
The chart only applies to liquids with a viscosity similar to that of water.
1. Determine the diameter ratio d/D.
2. From the chart, determine the pressure loss as a function of the flow velocity (after the
reduction) and the d/D ratio.

3.2.9 Nominal diameter and flow rate
The pipe diameter and the flow rate determine the nominal diameter of the sensor. Optimum flow
velocity is between 2 and 3 m/s. The flow velocity (v) must also match the physical properties of
the fluid:
v < 2 m/s: for abrasive fluids such as potter's clay, lime milk, ore slurry etc.
v > 2 m/s: for fluids that tend to cause buildup, such as wastewater sludge etc.
!Note!
If the flow velocity has to be increased, this can be achieved by reducing the nominal diameter of
sensor (→ä17).
