  • Page 3: Safety Instructions

    Micropilot M FMR244 PROFIBUS PA Safety instructions Safety instructions Designated use The Micropilot M is a compact radar level transmitter for the continuous, contactless measurement of liquids, pastes, sludge and solids. 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 6: Installation

    Mounting Micropilot M FMR244 PROFIBUS PA Installation 2.3.1 Mounting kit Beside a key AF 60 for installation you need the following tool: • 4 mm (0.16 in) Allen wrench for turning the housing. 2.3.2 General installation instructions • Marker is aligned towards tank wall.
  • Page 7 Micropilot M FMR244 PROFIBUS PA Mounting Standard installation - 80 mm (3.15 in) antenna • The marker is located directly below the housing neck on the stainless steel feedthrough. • As an option for flange mounting, a variable flange seal (see "Accessories") can be used to align the device (solid applications).
  • Page 8 Mounting Micropilot M FMR244 PROFIBUS PA 2.3.5 Orientation • Recommended distance (1) wall - outer edge of nozzle: ~1/6 of tank diameter. Nevertheless the device should not be installed closer than 15 cm (5.91 in) to the tankwall. • Not in the centre (3), interference can cause signal loss.
  • Page 9 Micropilot M FMR244 PROFIBUS PA Mounting 2.3.6 Engineering hints Tank installations • Avoid any installations (1), like limit switches, temperature sensors, etc., inside the signal beam (→ ä 10). • Symmetrical installations (2), i.e. vacuum rings, heating coils, baffles, etc., can also interfere with the measurement.
  • Page 10 Mounting Micropilot M FMR244 PROFIBUS PA 2.3.7 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 11 Micropilot M FMR244 PROFIBUS PA Mounting • For the measurement of absorbing gases such as ammonia NH or some fluorocarbons please use FMR230 in a stilling well. • The measuring range begins, where the beam hits the tank bottom. Particularly with dish bottoms or conical outlets the level cannot be detected below this point.
  • Page 12 Mounting Micropilot M FMR244 PROFIBUS PA 2.3.9 Measuring conditions in solids • The measuring range begins, where the beam hits the bottom. Particularly with conical outlets the level cannot be detected below this point. The maximum measuring range can be increased in such applications by using a top target positioner (see TI345F/00/EN).
