1. Welcome
Sincerely thank you for buying Radar level transmitter!
This manual introduces the application, feature, function, installation and setup of Radar level transmitter level
transmitter so that users can know, install, use and maintain this instrument.
2. Overview
ARL5000 is characterized by 26G electromagnetic wave and the measurement will be not affected by the influence of
noise, water vapor, temperature, pressure, dust, gas volatilization etc. With excellent anti-interference ability, it can work
effectively in harsh environments.
Equipped with a new micro processor, ARL5000 is more ideal in rate signal analysis, processing capacity, which greatly
improves the stability and accuracy of measurement. ARL5000 features in non-contact level measurement, simple
structure and easy installation and it can be widely used in complicated working conditions such as reaction kettle, solid
liquid silo, high temperature and high pressure.
3. Measuring Principle
The narrow microwave pulses are emitted via an antenna, reflected from the measured media surface and then received
by antenna system again. The received signals are transmitted to electronic circuit and some are automatically
converted to level signals. (The process, the electromagnetic wave reaches the target and is reflected back to the
receiver, occurs instantly. because the microwave travels very fast.)

7. Mounting
Please reserve enough installation space and try to avoid strong shock installation occasions.
A. Vaulted Tank
Be installed in the 1/4 or 1/6 of the vaulted tank diameter
Note: The minimum distance from the tank wall should be 200 mm.
Note: ①Datum plane
②The tank center or axis of symmetry
Min 200mm
①
②
B. Tapered Tank
Be installed in the flat-top middle of tapered tank to ensure that the bottom of the tank is measured

ARL5000 Operation Manual OP5000.1.1.7.R1ENG
8
C. Stacking Tank
The antenna should be perpendicular to the material surface. If the material surface is not flat and the pile angle is
large, a universal flange can be used to adjust the horn angle so that the horn can point at the material surface as
much as possible.
1/4 ID
Note: Inclined solid surfaces will cause echo attenuation and even signal loss.
D. Be not installed in the middle of vaulted or round tank roof. Because multiple echoes can be concentrated at the top,
and the echo signal may be larger than the signal threshold of the true echo.

ARL5000 Operation Manual OP5000.1.1.7.R1ENG

E. Be not installed above the material inlet or agitator, and outdoor protection measures are necessary such as
sunshade, rainproof, etc.
F. If obstacle signals exist in the tank, a reflector can be added to refract them away to ensure normal measurement.

G. Interference occurs when there are obstacles, such as ladder, heating device, agitators, etc. in the area radiated by
the emitted microwave beam. It is recommended the way of by-pass pipe installation.
By-pass Pipe Requirements:
Metal tube (optional plastic liner): to prevent radar signals from penetrating the tube wall to generate interference
echoes
Pipe diameter in uniform, and the difference between horn antenna diameter and waveguide inner diameter should be
as little as possible
Keep waveguide pipe inner wall smooth, the average surface finish of Rz ≤6.3 μm.
The way of by-pass pipe installation can not be used for measurement of adhesive medium
H. The way of waveguide pipe installation is recommended for frothy liquid or big fluctuations of level in the tank.
Venthole
Waveguide Tube Requirements:
Metal tube (optional plastic liner): to prevent radar signals from penetrating the tube wall to generate interference
echoes
Tube diameter in uniform, the difference between horn antenna diameter and waveguide tube inner diameter should
be as little as possible
Keep waveguide tube inner wall smooth, the average surface finish of Rz ≤6.3 μm
Equal pressure holes should be reserved to ensure the same liquid level inside and outside the waveguide tube
The way of waveguide tube installation can not be used for measurement of adhesive medium
Venthole diameter of 5-10 mm

ARL5000 Operation Manual OP5000.1.1.7.R1ENG
11
I. Nozzle Height Requirements:
The reflected wave generated by the end of the nozzle may affect the measurement result. So generally the horn
antenna needs to stick out of the nozzle.
The nozzle height must ensure that the distance of antenna sticking into the tank can not be less than 10 mm.
＞10mm
＞10mm
However, if the measured medium is with good reflective characteristics, the connected pipe can be longer than antenna
length. And the standard connected pipe length is shown as below chart. In this case, the end of the connected pipe can
never have burr and other protrusion and needed to be smoothed. If necessary, the ‘False echo memory (false echo
learning)’ function can be used to remove weak reflection from the end of the connected pipe.

J. Avoid measured liquid level reaching the blind zone, resulting in incorrect measurement
K. If the process temperature is high, an insulation layer must be added outside the tank to avoid electronics overheating
inside the instrument due to heat radiation or heat convection, but the insulation layer must not exceed the device neck.
