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.
