Technical Information
Micropilot S FMR540
Level-Radar
Smart 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 with parabolic antenna is excellently suited for
free space applications up to 40 m (131 ft).
• The 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 DN200 (8") parabolic antenna offers
high beam focussing of 4° 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.
TI412F/00/en/11.06
Your benefits
• Better than 1 mm accuracy.
• National approvals (NMi, PTB) for custody transfer.
• Applicable as stand-alone system or tied into tank
gauging systems via the Tank Side Monitor NRF590.
• Cost-effective and simple installation via 4-wire cable
with HART and 24V DC intrinsically safe power
supply.
• low cost, low weight UNIversal flanges
• top target positioners to compensate any flange
inclination
• easy on-site operation via menu-driven alphanumeric
display
• easy commissioning, documentation and diagnostics
via operating software (ToF Tool - Fieldtool Package or
FieldCare)
• HART communication.

  • Page 3: Function And System Design

    Micropilot S FMR540 Function and system design Measuring principle The Micropilot is a "downward-looking" measuring system, operating based on the time-of-flight method. It measures the distance from the reference point (process connection) to the product surface. Radar impulses are emitted by an antenna, reflected off the product surface and received again by the radar system.

The ToF Tool is a graphical operating software for instruments from Endress+Hauser that operate based on the time-of-flight principle (radar, ultrasonic, guided micro-impulse). It assists with commissioning, securing data, trouble shooting and documentation of the measuring point.

    The number of instruments which can be connected in mutidrop mode can be calculated by the "FieldNetCalc" program. A description of this program can be found in Technical Information TI 400F (Multidrop connector FXN520). The program is available form your Endress+Hauser sales organisation or in the internet at: "www.endress.com É Download" (Text Search = "Fieldnetcalc").

  • Page 8: Measuring Range

    Micropilot S FMR540 Measuring range The usable measuring range depends on the size of the antenna, the reflectivity of the medium, the mounting location and possible interference reflections. To achieve an optimised signal strength it is recommended to use an antenna with as large as possible diameter (DN200/8"...
  • Page 9: Measuring Conditions

    Micropilot S FMR540 Measuring conditions • 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. • In case of media with a low dielectric constant (groups A and B), the tank bottom can be visible through the medium at low levels (low height C).
