1 Safety instructions
1.1 Designated use
The Micropilot S FMR 532 is a compact radar level transmitter for the continuous,
contactless measurement of liquids, pastes and sludge in stilling wells. The device
can also be freely mounted outside closed metal vessels because of its operating
frequency of about 6 GHz and a maximum radiated pulsed energy of 1mW (average
power output 1
µ W). Operation is completely harmless to humans and animals.
1.2 Installation, commissioning and operation
The Micropilot S has been designed to operate safely in accordance with current
technical, safety and EU standards. If installed incorrectly or used for applications for
which it is not intended, however, it is possible that application-related dangers may
arise, e.g. product overflow due to incorrect installation or calibration. For this reason,
the instrument must be installed, connected, operated and maintained according to the
instructions in this manual: personnel must be authorised and suitably qualified. The
manual must have been read and understood, and the instructions followed.
Modifications and repairs to the device are permissible only when they are expressly
approved in the manual.
1.3 Operational safety
Hazardous areas
Measuring systems for use in hazardous environments are accompanied by separate
"Ex documentation", which is an integral part of this Operating Manual. Strict
compliance with the installation instructions and ratings as stated in this supplementary
documentation is mandatory.
•Ensure that all personnel are suitably qualified.
•Observe the specifications in the certificate as well as national and local regulations.
FCC-approval
This device complies with part 15 of the FCC Rules. Operation is subject to the following
two conditions: (1) This device may not cause harmful interference, and (2) this device
must accept any interference received, including interference that may cause
undesired operation.
"
Caution!
Changes or modifications not expressly approved by the part responsible for
compliance could void the user’s authority to operate the equipment.

1.4 Return
The following procedures must be carried out before a transmitter is sent to
Endress+Hauser for repair:
•Always enclose a duly completed "Declaration of contamination" form. Only then can
Endress +Hauser transport, examine and repair a returned device.
•Enclose special handling instructions if necessary, for example a safety data sheet as
per EN 91/155/EEC.
•Remove all residue which may be present. Pay special attention to the gasket grooves
and crevices where fluid may be present. This is especially important if the fluid is
dangerous to health, e.g. corrosive, poisonous, carcinogenic, radioactive, etc.
!
Note!
A copy of the “Declaration of contamination”is included at the end of this operating
manual.
"
Caution!
•No instrument should be sent back for repair without all dangerous material being
completely removed first, e.g. in scratches or diffused through plastic.
•Incomplete cleaning of the instrument may result in waste disposal or cause harm to
personnel (burns, etc.). Any costs arising from this will be charged to the operator of
the instrument.

3.3.2 Engineering hints
Measuring conditions
•The measuring range starts at the bottom end of the stilling well.
•In case of media with a low dielectric constant (groups A and B), the pipe end can be
visible through the medium at low levels. In order to guarantee the required accuracy
in these cases, it is recommended to position the zero-point at a distance Cabove the
tank bottom (see Fig.).
•In applications with planar or parabolic antennas, especially for media with low
dielectric constants (see page 15), the end of the measuring range should not be
closer than 1 m (40”) to the flange.
•For overspill protection, it is possible to define a safety distance (SD) additionally to
the blocking distance (BD).
•This safety distance (SD) is set to 0.5 m (20") by default and generating an alarm in
case the level rises inside the safety distance.
•Distance Bdefined the smallest recommended measurement range.
•Depending on its consistence, foam can either absorb microwaves or reflect them off
the foam surface. Measurement is possible under certain conditions.
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 (E681).

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.
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.
1) Treat Ammonia NH3 as a medium of group A, e.g. always use a stilling well.

Blocking distance
The blocking distance (= BD) is the minimum distance from the reference point of the
measurement (mounting flange) to the medium surface at maximum level.

3.4 Installation instructions
3.4.1 Mounting kit
In addition to the tool needed for flange mounting, you will require the following tool:
•4 mm Allen wrench for turning the housing.
3.4.2 Installation in stilling well
Optimum mounting position for FMR 532
Recommendations for the stilling well
•Metal (no enamel coating, plastic on request).
•Constant diameter.
•Weld seam as smooth as possible and on the same axis as the slots.
•Slots offset 180°(not 90°).
•Slot width respectively diameter of holes max. 1/10 of pipe diameter, de-burred.
Length and number do not have any influence on the measurement.
#
•Select antenna extension as big as possible. For intermediate sizes (e.g. 180 mm)
select next larger antenna extension and adapt it mechanically. Maximum gap
allowed between the antenna/horn of FMR 532 and the inside of the stilling well is
5 mm (3/16").
•The antennna extension of the FMR 532 is mounted with defined pressure.
It is strongly recommended not to dismantle this antenna.
•Dimensions of a nozzle for manual gauging must be adapted to the dimensions of the
horn antenna used, compare to page Page 23.
Stilling wells with pipe expansion
•When using a FMR 532, a gradual pipe expansion from DN150 to DN200 / DN200 to
DN250 / DN250 to DN300 is acceptable. In such cases, the top end of the piping must
have a minimum length of 0.5 m in front of the expansion (see table on Page 18).
Ideally, a dip socket is used for this.
•Greater expansion of the piping (e.g. DN150 to DN300) is possible if the top end of
the pipe is extended accordingly (see table on Page 18).
•Avoid pipe expansions at right angles.
Standard installation
When mounting in the stilling well, please
observe engineering hints on Page 14 and
the following points:
•After mounting, the housing can be
turned 350°in order to simplify access to
the display and the terminal
compartment.
•planar axis vertical to flange.
•Measurements can be performed
through an open ball valve without any
problems.

3.4.4 Installation with E+H UNI flange
Installation hints
E+H UNI flanges are designed for non-pressurized operation respectively max. 1 bar
absolute pressure. The number of bolts has sometimes been reduced. The bolt-holes
have been enlarged for adaption of dimensions, therefore, the flange needs to be
properly aligned to the counterflange before the bolts are tightened.
