Technical Information
Micropilot S FMR540
Level-Radar
Level transmitter for continuous and non-contact
precision level measurement
For custody transfer and inventory control
applications with NMi- and PTB-approvals.
Application
The Micropilot S is used for highly accurate level measurement in storage tanks and
can be applied in custody transfer applications. It meets the relevant requirements
according to OIML R85 and API 3.1B.
Typical areas of application are:
• The Micropilot S with parabolic antenna is excellently suited for free space
applications up to 40 m (131 ft).
• The Micropilot S with horn antenna is suitable for free space applications that
disallow the use of a parabolic antenna due to tank/nozzle geometry.
The FMR540 with a DN200 (8") or DN250 (10") parabolic antenna offers high beam
focussing of 4.4° or 3.3° respectively, and is therefore ideally suited to applications with
nozzles situated close to the tank wall. The FMR540 with DN100 (4") horn antenna is
designed for all small nozzles sizes.
Your benefits
• Accuracy: better than 1 mm (0.04 in).
• National approvals (NMi, PTB) for custody transfer.
• Easy integration into tank gauging systems via the Tank Side Monitor NRF590.
• Low-cost, easy installation via 4-wire cable with HART and 24 V DC (intrinsically
safe).
• Low cost, low weight universal flanges.
• Alignment device to compensate any flange inclination.
• Easy on-site operation via menu-driven alphanumeric display.
• Easy commissioning, documentation and maintenance/diagnostics via operating
software (FieldCare).
• HART communication.

  • Page 9 Micropilot S FMR540 The beam angle is defined as the angle D where the energy density of the radar waves reaches half the Beam angle value of the maximum energy density (3dB-width). Microwaves are also emitted outside the signal beam and can be reflected off interfering installations. The beam diameter W is a function of antenna type (beam angle D) and distance D.
