Standard installation
For installations in a stilling well, follow the engineering hints on Page 14 and note the
following points:
•
Marker is aligned perpendicular (90°) to tank connectors.
•
The marker is always exactly in the middle between two bolt-holes in the flange.
•
After mounting, the housing can be turned 350° in order to simplify access to the
display and the terminal compartment.
•
The horn must be aligned vertically.
•
Measurements can be performed through an open full bore ball valve without any
problems.
Recommendations for the bypass pipe
•
Metal (no plastic or enamel coating)
•
Constant diameter
•
Select horn antenna as big as possible. For intermediate sizes (i.e. 95 mm) select next
larger antenna and adapt it mechanically (FMR 230 / FMR 240 only).
•
At any transition (i.e. when using a ball valve or mending pipe segments), no gap may
be created exceeding 1 mm (0.04").
•
In the area of the tank connections (~ ±20 cm / 8“) a reduced accuracy of the
measurement has to be expected.
