FEATURES
PRINCIPLE
FMCW Radar level transmitter is a non contact
measuring device, which is suitable for high temp.,
high pressure, and corrosive applications. It is
easy to install and free of maintenance, especially
for the high accuracy requirement environment.
Design formula
High voltage : IEC60947-2
Isolated resistance : IEC60092-504
Power supply change : IEC60092-504
Power supply failure : IEC60092-504
Electrical burst testing : IEC61000-4-4
Voltage DIPS : IEC61000-4-11
Humidity : IEC60068-2-30
High/Low temperature test : IEC60068-2-38
IP protection rating : IEC60529
TEST STANDARDS
LINEARITY DIAGRAM
FMCW radar adopts a high frequency signal,
which is emitted via an antenna and swipe
frequency increment by 0.5GHz during the
measurement, reflected by the target surface and
received at a time delay. The frequency difference,
which is calculated from the transmitting frequency
and the received frequency, which is directly
proportional to the measured distance (or material
surface).
The frequency difference then is processed by
Fast Fourier Transformation (FFT) to identify the
signal in Intermedium Frequency (IF). This FMCW
radar is innate with signal / noise enhancement
and filtering of echo-back via Phase-Lock Loop
(PLL) circuit that is the best solution for complex
environment and high accuracy measurement.

5. Installation recommendations are as follows :
(1) Antenna installation angle to be perpendicular to the
Horizontal.
(2) JFR installation position with the drum wall suggestions
Are as follows :
Installation location A should be less than 1/6D
Range with A relation is as follows :
a. H<10m, A>300mm
b. 10m<H<20m, A >600mm
c. H>20m, A>900mm
(3)Extended tube is suggested to do the welding process
from outside; welding process from inside, the bulges
might affect the signal transmission. The joint part of
extended tube cannot be less than “D”.

10. If drum internal agitator will have a strong vortex and
foam, drum must increase waveguide, the upper
waveguide drill vent holes to ensure the correctness of
the measured value.
11. Installation should be avoided in the feed inlet position,
avoid material interference or obstacles interference.
12. Installation should be avoided in the top center of the
arch or round barrel will cause multiple echo reflections.

6. Radar installation should not be too close to the drum
wall, avoid the drum wall attachment material reflection
interference.
8. When obstructions inside the tank, tank be fitted with
eflectors, steer clear of the error echo reflected to the
receiver, causing radar miscalculation.
7. Radar installation not too close to the drum bracket to
avoid reflection is incorrect

3. Echo Pattern
From the echo pattern, the user may observe the echo curve of the current signal and make the settings
obtain the correct echo value by processing various signals (signal gain, filter setting, signal selection,
background noise, signal elimination). Press in the main menu and select the echo pattern 3. Then,
press to save the settings.
3.1 Signal Gains
As shown in the echo pattern, when the echo signal is so weak that the display value is unstable without
interference from other noise, this function can be used to magnify the echo signal. Press in the Echo
Pattern menu and select Signal Gains 3.1. Finally, press to save the settings.
Select the magnification rate by using or . The magnification rate is displayed by LVL on the upper
right of the echo pattern (LVL is 0001 by default). A total of 7 levels are available. Press to save the
settings, as described below.
3.2 Filter Setting
This function is applied to the great fluctuation or bubble generated on the liquid surface, which causes
the echo signal to become unstable. It is used when the display value is unstable. Press in the Echo
Pattern menu and select Filter Setting 3.2. Then press to save the settings.
The default value is 10, which can be adjusted by pressing or . After the setting is finished,
press to save. If the display value is still unstable after the setting, increase the value for test again.
