1 Safety instructions

1.1 Designated use

The Micropilot M FMR 245 is a compact radar level transmitter for the continuous, contactless
measurement of liquids, pastes and sludge. 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 1mW (average power output 1 μW). Operation is completely harmless to humans and
animals.

1.2 Installation, commissioning and operation

The Micropilot M 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

1.3.1 Hazardous areas

3.3.2 Engineering hints

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 (6“) to the
tankwall.

• 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 (→ Chap. 8 on Page 67).

L00-FMR2xxxx-17-00-00-xx-010

234

Tank installations

• Avoid any installations (1), like limit switches,
temperature sensors, etc., inside the signal
beam (refer to beam angle see "Beam angle"
on Page 15).

• Symmetrical installations (2), i.e. 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: refer to "optimum
mounting position"

• Stilling well: a stilling well can always be used
to avoid interference.

• Metallic screens (3) mounted at a slope spread
the radar signals and can, therefore, reduce
interference echoes.

Please contact Endress+Hauser for further infor­mation.

Measurement in a plastic tank

If the outer wall of the tank is made of a non-conductive material (e.g. GRP), microwaves can also
be reflected off interfering installations outside the signal beam (e.g. metallic pipes (1), ladders (2),
grates (3), …). Therefore, there should be no such interfering installations in the signal beam.

The beam angle is defined as the angle a 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 W as function of
antenna type (beam angle α) and measuring distance D:

Measuring conditions

L00-FMR2xxxx-17-00-00-de-013

• 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). 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 FMR230/231/240.
However, due to considerations regarding corrosion and build-up, the end of the measuring range
should not be chosen any closer than A (see Fig.) to the tip of the antenna.
For FMR244/245, the end of measuring range should not be chosen closer than A (see Fig.) to
the tip of the antenna, especially if there is development of condensate.

• The smallest possible measuring range B depends on the antenna version (see Fig.).

• The tank diameter should be greater than D (see Fig.), the tank height at least H (see Fig.).

Note!

• In case of boiling surfaces, bubbling or tendency for foaming, use FMR230 or FMR231.
Depending on its consistence, foam can either absorb microwaves or reflect them off the foam
surface. Measurement is possible under certain conditions.

• In case of heavy steam development or condensate the max. measuring range of FMR240 may
decrease depending on density, temperature and composition of the steam → use FMR230 or
FMR231.

• For the measurement of absorbing gases such as ammonia NH

3

or some fluorocarbons

1))

,

please use FMR230 in a stilling well.

1) Affected compounds are e.g. R134a, R227, Dymel 152a.

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 maximum configurable range is:

• 20 m (65 ft) for Micropilot M FMR23x,

• 20 m (65 ft) for Micropilot M FMR24x,
– 40 m (131 ft) for Micropilot M FMR24x with additional option D (E), see "ordering

information",

– 70 M (229 ft) for Micropilot M FMR24x with additional option F (G), see "ordering

information",

• 70 m (229 ft) for Micropilot M FMR250 (further informations see TI390F/00/en).

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.

Media group DC (εr) Examples

A 1,4...1,9 non-conducting liquids, e.g. liquefied gas

1))

1) Treat Ammonia NH3 as a medium of group A, i.e. use FMR230 in a stilling well.

B 1,9...4 non-conducting liquids, e.g. benzene, oil, toluene, …

C 4...10 e.g. concentrated acids, organic solvents, esters, aniline, alcohol, acetone, …

D > 10 conducting liquids, e.g. aqueous solutions, dilute acids and alkalis

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/0.1" Allen wrench for turning the housing.

3.4.2 Installation in tank (free space)

Optimum mounting position

L00-FMR245xx-17-00-00-en-003

Standard installation

When mounting in a tank, please observe engineering hints on Page 13 and the following points:

• Marker is aligned towards tank wall.

• The marker is always exactly in the middle between two bolt-holes in the flange.

• Use spring washers (1) (see Fig.).
Note!
It is recommended to retighten the flange bolts periodically, depending on process temperature
and pressure. Recommended torque: 60...10 Nm.

• After mounting, the housing can be turned 350° in order to simplify access to the display and the
terminal compartment.

• The antenna must be aligned vertically.
Caution!
The maximum range may be reduced, if the antenna is not vertically aligned.

3.4.3 Installation in stilling well

Optimum mounting position

L00-FMR245xx-17-00-00-en-004

Standard installation

For installations in a stilling well, follow the engineering hints on Page 13 and note the following
points:

• Marker is aligned toward slots.

• The marker is always exactly in the middle between two bolt-holes in the flange.

• After mounting, the housing can be turned 350° in order to simplify access to the display and the
terminal compartment.

• Measurements can be performed through an open full bore ball valve without any problems.

Recommendations for the stilling well

At the construction of a stilling well, please note the following points:

• Metal (no enamel coating, plastic coating on request).

• Constant diameter.

• Stilling well diameter not larger than antenna 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.

• At any transition (i.e. when using a ball valve or mending pipe segments), no gap may be created
exceeding 1 mm.

• The stilling well must be smooth on the inside (average roughness Rz ≤ 6.3 μm). Use extruded
or parallel welded stainless steel pipe. An extension of the pipe is possible with welded flanges or
pipe sleeves. Flange and pipe have to be properly aligned at the inside.

• Do not weld through the pipe wall. The inside of the stilling well must remain smooth. In case of
unintentional welding through the pipe, the weld seam and any unevenness on the inside need
to be carefully removed and smoothened. Otherwise, strong interference echoes will be generated
and material build-up will be promoted.

3.4.4 Installation in bypass

Optimum mounting position

L00-FMR230xx-17-00-00-en-007

Standard installation

For installations in a bypass, follow the engineering hints on Page 13 and note the following points:

• Marker is aligned perpendicular (90°) to tank connectors.

• The marker is always exactly in the middle between two bolt-holes in the flange.

• After mounting, the housing can be turned 350° in order to simplify access to the display and the
terminal compartment.

• Measurements can be performed through an open full bore ball valve without any problems.

Recommendations for the bypass pipe

• Metal (no plastic or enamel coating)

• Constant diameter

• Select horn antenna as big as possible. For intermediate sizes (i.e. 95 mm) select next larger
antenna and adapt it mechanically (FMR 230 / FMR 240 only).

• At any transition (i.e. when using a ball valve or mending pipe segments), no gap may be created
exceeding 1 mm (0.04").

• In the area of the tank connections (~ ±20 cm / 8“) a reduced accuracy of the measurement has
to be expected.

Supply voltage

The following values are the voltages across the terminals directly at the instrument:

Power consumption

Normal operation: min. 60 mW, max. 900 mW

Current consumption

Overvoltage protector

The level transmitter Micropilot M with T12-housing (housing version "D", see ordering
information) is equipped with an internal overvoltage protector (600 V surge arrester) according to
DIN EN 60079-14 or IEC 60060-1 (impulse current test 8/20 μs, Î = 10 kA, 10 pulses). Connect
the metallic housing of the Micropilot M to the tank wall or screen directly with an electrically
conductive lead to ensure reliable potential matching.
