Mounting: Rod Assembly
Ideally, the stand pipe should be as short as possible. If
your application requires a stand pipe that exceeds our
recommended maximum lengths, consider using a
waveguide and horn combination. If you create a new
stand pipe for the radar unit, ensure the weld seams are
on the outside of the stand pipe, not the inside.
Ensure that there are no seams or lips on the inside of
the stand pipe or you may get erratic readings.
If the mounting illustrated above is not suitable due to the minimum blanking
requirements, consider the following option:
enclosure
minimum diameter 100mm (4”)
A
Installation
Stand pipes that are 8” or larger in diameter provide excellent signal
conditions. These conditions allow for stand pipe lengths of up to 24” using
the standard rod without any extensions.

Mounting: Manhole Covers
A manhole cover is typically a stand pipe that is 24” in diameter or greater and
that have a cover.
To provide the optimum signal conditions, locate the antenna off-centre with
respect to the cover, typically 100 mm (4”) from the side of the manhole.
100 mm (4”)
Mounting: Horn Antennas
Usually, horns are mounted on short stand pipes.
Installation
The end of the horn should
protrude a minimum of 10 mm
(0.5”) to avoid interference with
the stand pipe.

Suitable pipe diameters are 2” (50 mm) to 10” (250 mm). A rod antenna or a
horn antenna may be used.
Note: The measurement range is reduced to 13 m (43’) for a 50 mm (2”)
still pipe or 14.5 m (47’) for a 80 mm (3”) still pipe.
Smoothness
One continuous length of metallic pipe is preferred (no joints). If joints are
required due to long length, then you must machine the joints to close
tolerances ± 0.25mm (± 0.010”) and weld a connecting sleeve on the outside.

You can use either a
Rod or Horn antenna.
Ensure there is a vent at the upper end of the surge pipe to equalize pressure
and keep the liquid level in the pipe constant with level in the vessel.

Mounting: Horn with Waveguide Extensions
In applications where the stand pipe is too
long and the diameter is too small (such as a
stand pipe that is 100 mm (4”) in diameter
and 460 mm (18”) in length), the rod antenna
is not suitable due to stand pipe interference.
In this case, use the waveguide / horn
combination. Waveguide extensions are
available in custom lengths.
If the horn diameter is too large for the stand
pipe opening, you need to insert it from inside
the vessel. The horn must be connected to
the IQ160 process flange.
Note: The IQ160 maximum range of 15m is reduced by [0.64 x waveguide
length]. Blanking and offset parameters will be set by Milltronics, see the
device tag for values.

Polarization Effect
Mounting the unit too close to a wall may cause echoes to d isappear at
specific levels due to wave cancellation. A strong false reflection from an
internal tank obstruction can be reduced or eliminated by rotating the unit to
reduce the polarization effect.
False Reflections
Flat obstructions, and struts that are perpendicular to the emission cone,
cause large false reflections. They reflect the radar signal with high amplitude.
Round profile interfering surfaces diffuse reflections of the radar signals and
cause false reflections with low amplitude.

Operation
Overview
The IQ Radar 160/160 Ex is a level measuring device for use with liquids and
slurries. Using advanced pulse radar technology, the device calculates
material level by first emitting a series of radar pulses and then analyzing their
reflections.
The device consists of an enclosed electronic component, mounted to a
flanged antenna component. The electronic component generates a 5.8 GHz
(U.S.A. 6.3 GHz) radar signal, which is directed to the antenna, waveguide, or
horn.
The radar signal is emitted axially from the antenna and propagates along this
axis in a defined conical beam decreasing in strength at a rate inversely
proportional to the distance.
The radar pulse detects the interface between the dielectric constant of the
atmosphere, and that of the material being measured. Electro-magnetic wave
propagation is not sensitive to the temperature and atmospheric conditions or
variations in the vessel.
The series of echoes from the pulses transmitted are sensed by the antenna
during the receive period of the electronics. The echoes are stored as a
profile of the activity in the vessel. The profile is analysed and the distance of
the material surface to the radar antenna is determined. This distance is used
as a basis for display of material level and mA output.
Transceiver
The IQ Radar 160/160 Ex transceiver operates under 1 of 5 sets of preset
conditions (P003), summarized as follows:
parameter
value
1 0.1 m/min slow on on 100
2 1 m/min • on on 10
3 10 m/min • on on 1
4 100 m/min • off on 0.1
5 1000 m/min fast off off 0
measurement
response
echo
verification filter
fail-safe
timer
Operation
When the echoes are received, the relevant echo extraction technique (P820
and P830) is applied to determine the true material echo.
PL-550 IQ Radar 160/160 Ex Page 41
Page 42
The measurement response limits the maximum rate at which the display and
analog output respond to changes in measurement. It is of concern especially
where liquid surfaces are in agitation or fall into the radar path during filling.
Loss of Echo
A loss of echo occurs when the IQ Radar 160/160 Ex deems that the
calculated measurement is unreliable, i.e. the confidence (P805) is less than
the threshold (P804). Refer to Troubleshooting on page 63.
If the condition persists for a time beyond the limit as set by the fail-safe timer
(P070), the confidence icon changes from full to partial (see page 36) and the
reading and mA output are immediately forced to the fail-safe default (P071).
Upon receiving a reliable echo, the loss of echo condition is aborted (icon
returns to full) and the reading and mA output return to the present level
immediately.
Blanking
Near blanking (P800) is used to ignore the zone in front of the antenna where
false echoes (e.g. ladder rung) appear as an echo during the receive cycle.
This is usually indicated by an incorrect high level reading and can be
overcome by increasing the near blanking from its factory set value.
Far end blanking is a feature that ignores the zone below the zero or empty
level where false echoes can appear at levels that interfere with the
processing of the true echo.

range
Page 43
In applications where the zero level is above the bottom of the vessel and it is
desired to monitor the zone below the normal zero, range extension (P801)
can be used to extend the range into the far end blanking. Range extension is
entered as a percentage of P006. As range extension reduces the protection
afforded by the far end blanking, it should be used judiciously. Avoid
excessive range extension as this can reduce the measurement’s reliability
and accuracy. Range extension is factory set for 5% of P006. If it is found that
false echoes are appearing, after the blanking zone, P801 should be
increased accordingly.
Analog Output
The IQ Radar 160/160 Ex can be programmed to provide an analog output
(P200) of 0 to 20 or 4 to 20 mA, and for proportional or inverse span.
Programming
Upon entering the Program mode, the analog output level holds its prior
value.

P652 Offset Correction
An offset value can be applied to the reading as a correction to the
measurement.
Note:
This parameter is automatically set when you enter parameter P004. In
addition, this parameter may have been factory set to a specific value to
accommodate options such as horn and waveguide antenna systems. A
Parameter Descriptions
tag on the instrument will specify the P652 value when these options have
been supplied.
Values:
-999 to 9999
Factory = 0
P655 Propagation Factor
The propagation factor (p.f.) is used to compensate for the change in the
microwave velocity, as compared with propagation in free space, when
propagation is within a still pipe (metal).
pipe size (i.d.) Propagation Factor
50 mm (2”) 0.827
80 mm (3”) 0.915
100 mm (4”) 0.955
150 mm (6”) 0.980
200 mm (8”) 0.990
Consult the factory for other sizes and propagation factor numbers.
Note: For waveguide antennas used as still pipes, this value is provided
on the product tag.
The propagation factor is constant for a
given pipe diameter, or can be determined
by comparing the radar distance reading
to the actual process material distance
(measured from the face of the IQ 160
flange).

into the measurement range. See Blanking on page 42.
Enter value in units of P005.
Factory = 0.4m
Note: This parameter may be set at the factory, if so the appropriate
values appears on the product tag.
P801 Range Extension
Sets the amount of range extension as measured from the empty distance
(P006) and extending into the far end blanking. See Blanking on page 42.
Enter as a % of P006, the distance below empty not blanked.
Factory = 5%
On tanks with conical or parabolic bottoms, it may be helpful to increase this
parameter to ensure that an empty tank reads empty.
Parameter Descriptions
P804 Confidence Threshold
The minimum echo confidence in dB that the echo must meet in order to
prevent a loss of echo condition and the expiration of the fail-safe timer
(P070).
Enter value in the range of 0 to 99.
Factory = 5
P805 Echo Confidence
A measure of echo reliability.
P806 Echo Strength
