Micropilot FMR56, FMR57

Optimization options
• Antenna size
The bigger the antenna, the smaller the beam angle a and the fewer interference echoes (® ä 34).
• Mapping
The measurement can be optimized by means of electronic suppression of interference echoes.
• Antenna alignment
Take into account the marker on the flange or threaded connection (® ä 39).
• Metallic screens mounted at a slope (3)
They spread the radar signals and can, therefore, reduce interference echoes.
• Variable flange seal (FMR56)
Using the variable flange seal, the device can be aligned in the direction of the product surface. For details
refer to Operating Instructions BA01048F, chapter "Accessories".
• Alignment device for FMR57
In FMR57 with alignment device, the sensor can be optimally aimed within the vessel and thus
interference echoes can be avoided. The maximum angle b is ±15°.
In particular, sensor alignment serves to:
– prevent interference reflections
– extend the maximum possible measuring range in conical outlets.
