  • Page 3: Safety Instructions

    Micropilot M FMR250 FOUNDATION Fieldbus Safety instructions Safety instructions Designated use The Micropilot M is a compact radar level transmitter for the continuous, contactless measurement of liquids, pastes and sludge. The device can also be freely mounted outside closed metal vessels because of its operating frequency of about 26 GHz and a maximum radiated pulsed energy of 1 mW (average power output 1μW).

  • Page 7 Micropilot M FMR250 FOUNDATION Fieldbus Mounting Standard installation FMR250 with parabolic antenna • Ideally the parabolic antenna should protrude from the nozzle (1). Particularly when using the top target positioner, please ensure that the parabolic reflector is protruding from the nozzle/roof so as not to inhibit alignment.
  • Page 8 Mounting Micropilot M FMR250 FOUNDATION Fieldbus 2.3.4 Mounting with top target positioner Using top target positioner it is possible to tilt the antenna axis by up to 15° in all directions. The top target positioner is used for the optimum alignment of the radar beam with the bulk solids surface.
  • Page 9 Micropilot M FMR250 FOUNDATION Fieldbus Mounting 2.3.6 Orientation • Recommended distance (1) wall - outer edge of nozzle: ~1/6 of tank diameter. Nevertheless the device should not be installed closer than 20 cm (7.87 in) to the tankwall. Note! If the tank wall is not smooth (corrugated metal, welding seams, irregularities etc.)
  • Page 10 Mounting Micropilot M FMR250 FOUNDATION Fieldbus 2.3.7 Engineering hints Vessel installations • Avoid any installations (1), like limit switches, struts, etc., inside the signal beam (→ ä 11). • Symmetrical installations (2), i.e. reinforcing rings, heating coils, etc., can also interfere with the measurement.
  • Page 11 Micropilot M FMR250 FOUNDATION Fieldbus Mounting 2.3.8 Beam angle α The beam angle is defined as the angle where the energy density of the radar waves reaches half the value of the maximum energy density (3dB-width). Microwaves are also emitted outside the signal beam and can be reflected off interfering installations.
  • Page 12 Mounting Micropilot M FMR250 FOUNDATION Fieldbus 2.3.9 Measuring conditions • The measuring range begins, where the beam hits the vessel bottom. Particularly with dish bottoms or conical outlets the level cannot be detected below this point. The maximum measuring range can be increased in such applications by using an alignment unit (→ ä 10).
