• Not in the centre (3), interference can
cause signal loss.
• Not above the fill stream (4).
• It is recommended to use a weather pro-
tection cover (2) in order to protect the
transmitter from direct sun or rain.

2.3.6 Engineering hints
Tank installations
• Avoid any installations (1), like limit
switches, temperature sensors, etc., inside
the signal beam (→ä10).
• 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
BA249F/00/EN.
• 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.
• For mounting in solid applications use the
variable flange seal to align the device
towards the product surface (see
TI345F/00/EN, "Accessories").
Please contact Endress+Hauser for further
information.

2.3.7 Beam angle
The beam angle is defined as the angle α 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 Was function
of antenna type (beam angle α) and measuring distance D:
2.3.8 Measuring conditions in liquids
• 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
È use FMR230 or FMR231.

• For the measurement of absorbing gases such as ammonia NH3or some fluorocarbons1),
please use FMR230 in a stilling well.
• 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 Bdepends on the antenna version (see Fig.).
• The tank diameter should be greater than D(see Fig.), the tank height at least H(see Fig.).

2.3.9 Measuring conditions in solids
• The measuring range begins, where the beam hits the bottom. Particularly with conical outlets
the level cannot be detected below this point.
The maximum measuring range can be increased in such applications by using a top target
positioner (see TI345F/00/EN).
• In case of media with a low dielectric constant (groups A and B), the bottom 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 bottom (see Fig.).
• In principle it is possible to measure up to the tip of the antenna with the Micropilot M.
However, due to considerations regarding abrasion and build-up and depending on the
orientation of the product surface (angel of repose), the end of the measuring range should be
at a distance of A(see Fig). If required, and if some conditions (high DC value, flat angle of
repose) are met, shorter distances can be achieved.

3.7 Screening/potential matching
• You achieve optimum screening against disturbances if the screening is connected on both
sides (in the cabinet and on the device). If you have to reckon with potential equalisation cur-
rents in the plant, only earth screening on one side, preferably at the transmitter.
• When using in hazardous areas, you must observe the applicable regulations and the separate
Ex documentation.
3.8 Degree of protection
• with closed housing: IP65, NEMA4X (higher degree of protection e. g. IP68 on request)
• with open housing: IP20, NEMA1 (also ingress protection of the display)
• antenna: IP68 (NEMA6P)
"Caution!
Degree of protection IP68 NEMA 6P applies for M12 PROFIBUS PA plugs only when the
PROFIBUS cable is plugged in.
3.9 Post-connection check
After wiring the measuring instrument, perform the following checks:
• Is the terminal allocation correct (→ä16)?
• Is the cable gland tight?
• Is the M12 plug screwed tight?
• Is the housing cover screwed tight?
• If auxiliary power is available:
Is the instrument ready for operation and does the liquid crystal display show any value?

4Operation
4.1 General structure of the operating menu
The operating menu is made up of two levels:
•Function groups (00, 01, 03, …, 0C, 0D):
The individual operating options of the instrument are split up roughly into different function
groups. The function groups that are available include, e.g.: "basic setup", "safety
settings.", "output", "display", etc.
•Functions (001, 002, 003, …, 0D8, 0D9):
Each function group consists of one or more functions. The functions perform the actual
operation or parameterisation of the instrument. Numerical values can be entered here and
parameters can be selected and saved. The available functions of the "basic setup" (00)
function group include, e.g.: "tank shape" (002), "medium property" (003), "process
cond." (004), "empty calibr." (005), etc.
If, for example, the application of the instrument is to be changed, carry out the following pro-
cedure:
1. Select the "basic setup" (00) function group.
2. Select the "tank shape" (002) function (where the existing tank shape is selected).
4.1.1 Identifying the functions
For simple orientation within the function menus, for each function a position is shown on the
display.
L00-FMRxxxxx-07-00-00-en-005
The first two digits identify the function group:
•basic setup 00
•safety settings 01
•linearisation 04
