2 . Measurement Principle
Principle
The extremely narrow microwave pulse emitted by the antenna on radar level instrument
can travel at the speed of light and part of its energy, which is reflected off the surface of
target medium, is received by the very same antenna. The time lapse between pulse emission
and reception by the antenna is proportional to the distance between the surface of target
medium and the reference point on antenna. However, due to the fact that the electromagnetic
wave is transmitted at extremely high speed, which leads to the tiny time lapse (nanosecond
level) and makes it difficult to be identified, GDRD series of radar level instrument have
adopted a special demodulation technology, enabling itself to detect the time lapse between
pulse emission and reception correctly, and eventually generate accurate measurement result.
Features
The pulse radar level instrument, adopted K band range as transmission frequency, which
make this series have specialties as below: Small beam angle, which centralize energy, make
GDRD high ability of anti-jamming, hence high accuracy and reliable. Small antenna size,
easy to mount and easy to equip extra dust protection. Small blind zone, good accuracy

Equipped with advanced microprocessor and unique EchoDiscovery echo processing
technology, the radar level instrument can be used under various hazardous process conditions
The pulse radar level instrument, with pulses as its working tool and extremely low
emission power, can be mounted on various metal or nonmetal vessels, harmless towards
the environment and human beings.

4 . Mounting Requirements
Basic Requirements
There is a certain existing beam angle while the antenna transmitting microwave pulses. There should be no barriers
between the lower edge of antenna and surface of measured medium. Therefore it is highly recommended to avoid
facilities inside vessels, such asladders, limit switches, heating spirals, struts and etc, during the mounting process.
“False echo learning” must be carried out during the installation in this case. Furthermore, microwave beams must
NOT intersect the filling streams. Be cautions during the installation: the highest level of target medium must NOT
enter into blanking zone; the instrument must keep certain distance to vessel walls; every possible measure needs
to be taken to position the instrument so that the direction of antenna emission is perpendicular to the surface of
measured medium. The installation of instruments in explosion proof area must abide by relevant local or federal
safety regulations. Stainless steel housing should be used for intrinsically safe explosion proof version, which is also
applicable in explosion proof areas. The instrument must be connected with ground in this case.

Pulse Radar Level Instrument
Damp-proof
In order to avoid dampness under
outdoor or humid indoor conditions
or for those instruments mounted
on cooling/heating vessels, seal
rings used on cables should be
screwed tight, plus the cable must
be bended downward outside
cable entry, indicated on the
diagram below
Antenna Extension
>10mm
The transducer end must at
least protrude 10mm out of
socket.
GDRD56 Antenna Extension
If the senser is mounted in a
socket extension that is too long,
strong false echoes are generated
which enterfere with the measurement.
Make sure that the horn antenna
protrudes out of the socket piece.

Rights and Wrongs in Mounting
A大 约 1 3 D

1.Correct
2.Wrong:Instruments are mounted
in the center of concave or arched
vassel tops, which results in
multiple echoes.
1.Wrong: Mount the instrument
in/above filling stream, which
results in the measurement of
filling stream not the target medium.
2.Correct:
Pulse Radar Level Instrument
Reflection board installation
If there are barriers in vessels， it is
required to mount baffle-board, by
doing this, the echo reflected by the
barrier will be reflected out. And “False
Echo Storage” will be applied.
Agitator
If there are agitators in vessels,
instrument must be mounted as
far away from agitators as possible.
Once installation completed, a
"false echo learning" should be
carried out while agitators in
motion to eliminate negative
influence caused by false echo
of agitators. You are advised to
opt for installation with standpipe
if foam or wave is generated due
to the action of agitators.
11
Installation with Standpipe
By using standpipe, the influence of foams can be reduced.
Side through Standpipe
installation with Standpipe
ventilation hole
You are advised to opt for installation
with standpipe (or bypass tube) to avoid
the influence on measurement caused
by barriers inside vessels or foam
generation.
It is advised to install antenna inside
of the standpipe to avoid the error
caused by foam. The minimum inner
diameter of standpipe should be 50mm.
Avoid large cracks or welding seam
when connecting standpipe. False
echo storage must be carried out as
well in this case.
Note: You must NOT mount instrument inside standpipe while
measuring adhesive medium.

5 Electrical Connection
Power Supply
20mA/HART(2-Wire) Power supply and current signal are carried by the same two-wire connection cable.
This equipment is not allowed to be connected to public utility power lines.
See the Technical Specifications of this guide for detailed requirement on power
supply. A safety barrier should be placed between power supply and instrument for
intrinsically safe version.
See the Technical Specifications of this guide for detailed requirement on power supply.
Earth-connected current output can be used for standard version of level instruments,
while the explosion proof version must be operated with a floating current output. Both
instruments and earth terminals should be connected with ground firmly and securely.
Normally you can either choose to connect with the earth terminal on vessel or adjacent
ground in case of plastic vessels.
Cable Connection
General Introduction
Standard 2-wire cable with outside diameter of 5...9mm, which assures the seal effect
of cable entry, can be used as feeder cable. You are recommended to use screened
Shielding & Grounding
The two ends of shielded cable must be connected with earth terminal. The shielded
cable must be connected with inner earth terminal directly inside the transducer, while
the outside earth terminal on housing must be connected with ground. In the event of
earth-connected current, the shielding side of shielded cable must be connected to
ground potential via a ceramic capacitor (e.g. : 1μF 1500V) in order to dampen the low
frequency grounding current and avoid the disturbance caused by high frequency signals
