2.2 Selecting the SDM location
The following guidelines apply to all SDM:
Install the SDM with 5xD length of straight pipe length upstream and 3xD of straight pipe length
downstream.
Avoid installation in a pipe section where the SDM tip may wear fast
Avoid installation near dosing valves.
Vertical pipe installation is preferred when the flow goes in upstream direction, see chapter
2.2.1.
Horizontal pipe installation: Sensor must be installed sidewise, see chapter 2.2.2.
