3.3 Installation conditions
3.3.1 Engineering hints
Orientation
• Recommended distance (1) wall - outer
edge of nozzle: ~1/6 of tank diameter
("Beam angle", ä12).
• Not in the centre (3), interference can
cause signal loss.
• Not above the fill stream (4).
• It is recommended to use a weather
protection cover (2) in order to protect the
transmitter from direct sun or rain.
Assembly and disassembly is simply done
by means of a tension clamp ("Accessories",
ä63).
A0020541

234
Tank installations
• Avoid any installations (1), like limit
switches, temperature sensors, etc., inside
the signal beam ("Beam angle", ä12).
• It is essential that HiHi alarm is below the
blocking distance (BD) and the safety
distance (SD).
• Symmetrical installations (2), e.g. vacuum
rings, heating coils, baffles, etc., can also
interfere with the measurement.
Optimization options
• Antenna size: the bigger the antenna, the
smaller the beam angle, the less
interference echoes.
• Mapping: the measurement can be
optimized by means of electronic
suppression of interference echoes.
• Antenna alignment:
"Optimum mounting position", ä15.
• Stilling well: a stilling well can always be
used to avoid interference. The FMR532
with planar antenna is recommended for
stilling wells with a diameter DN150 (6")
and larger.
• Metallic screens (3) mounted at a slope
spread the radar signals and can,
therefore, reduce interference echoes.
Please contact Endress+Hauser for further
information.

Beam angle
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. Beam
diameter Wis a function of antenna type (beam angle ) and measuring distance D. The
recommended distance to the tank wall is indicated in the tables below. It is strongly
recommended to avoid any mechanical obstacles within the highlighted area.

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.
• Depending on its consistence, foam can either absorb microwaves or reflect them off the
foam surface. Measurement is possible under certain conditions.
• The smallest possible measuring range Bdepends on the antenna version (see fig.).
• Tank diameter and height should be at least dimensioned such that a reflection of the
radar signal on both sides of the tank can be avoided.
• In case of media with a low dielectric constant (media groups A and B), the tank bottom
can be visible through the medium at low levels (low height C). Reduced accuracy has to
be expected in this range. If this is not acceptable, we recommend positioning the zero
point at a distance C(see Fig.) above the tank bottom in these applications.
• In principle it is possible to measure up to the tip of the antenna with FMR540. However,
due to considerations regarding accuracy corrosion and build-up, the end of the measuring
range should not be chosen any closer than 60 mm (2.36 in) to the tip of the antenna (see
Ain Fig.).
A0020737
Behaviour if measuring range is exceeded
The behaviour in case of the measuring range being exceeded can be freely set:
The default setting is a current of 22 mA and the generation of a digital warning (E651).

Measuring range
The usable measuring range depends on the size of the antenna, the reflectivity of the
medium, the mounting location and eventual interference reflections. To achieve an
optimised signal strength it is recommended to use an antenna with as large as possible
diameter (DN200(8") or DN250 (10") parabolic antenna).
The following tables describe the groups of media as well as the achievable measuring range
as a function of application and media group. If the dielectric constant of a medium is
unknown, it is recommended to assume media group B to ensure a reliable measurement.
Measuring range depending on sensor type and media group
Media group DC (r) Examples
A1 1.4 to 1.6 Propane, butane
A2 1.6 to 1.9 Non-conducting liquids, kerosene, jet fuels, gasoline, LPG
B1.9 to 4 Non-conducting liquids, e.g. gasline, diesel fuel, heavy oil, motor oil, asphalt,

FMR540 with alignment device
Micropilot S should be installed vertically towards the Liquid surface for best measuring
performance of ±1 mm (0.04 in). Using the alignment device it is possible to tilt the antenna
axis by up to 15° in all directions. The alignment device is used for the optimum alignment
of the radar beam to the liquid surface. The Sensor should be positioned vertical to the liquid
surface in inclination of 0° for Parabolic Antenna and up to 3° for Horn Antenna.
