Inlet and outlet runs
The sensor should be mounted away
from fittings liable to generate
turbulence (e.g. valves, elbows,
T-junctions).
Inlet run: > 3...5 x DN
Outlet run: > 2 x DN
Mounting location
Correct measurement is only possible
when the pipe is full. Consequently the
following locations should be avoided:
• No installation at the highest point
(air accumulation).
• No installation immediately before an
open pipe outlet in a downward line.
The installation shown in Fig. 12,
however, permits such a location.
Partly filled pipes
For inclines a mounting similar to a drain
should be adopted. Do not mount at the
lowest point (risk of solids collecting).
Added security is offered by Empty Pipe
Detection (EPD). This option has an
extra electrode in the measuring pipe
(standard with Promag F sensor).
Note!
Here, too, the inlet and outlet lengths
should be maintained.
