1.3. Working Princible

Microwave pulses emitted by the antenna of the radar move at the speed of light and as part of its energy, reflected by the surface of the medium

to be measured, recieved by the same antenna. The time between the emission and the arrival of the pulses (flight time) is proportional to the available

distance between the antenna and the surface of the medium to be measured.

The electromagnetic wave travels at a very high speed (nanoseconds) so it is difficult to describe it. Guided adar (T D) Type Level transmitter

determine the emission and corrected capacity of pulses and consequently the level measurement with a suitable demodulation tehcnology that enables

them to detect the between them, thanks to their integrated management systems. The alphanumeric display not only allows the user to input data for level

measurement, but also separates false echoes.

1.9. Package contents :

Please check whether you have taken delivery of below listed content completely or not and check its conformity with criterions

in your order:

The measurements maximum level, is the thread seal position or flanges bottom surface.

When the liquid or solid level is full, enter the dead zone correctly otherwise the instrument will not be able to measure the level effectively.

Mounting site selection

.6. Mounting Requirements

During the installation , while the tank is empty, false echo detection should be made and the surfaces that create faulty echo should be

recorded by the sensor. In this way, the sensor does not detect these points as a level and the measurement continues properly.

Care should be taken that the product entering the tank does not pass over the signal line of the sensor when filling through the silo or tank.

There is a blind area that cannot be measured by the sensors and known as the dead zone just below the antenna, which does not exceed

5 cm according to the sensor. It is important that the product does not pass over the sensors dead zone during filling, in which case

the sensor will fail or the measurement values may remain constant.

Mounting site selection

Safe Rope Probe

You can fix the probe with the outer tube

to prevent the rope probe from shaking.

Safe Rod Probe

Support is required when the probe

length is more than 3m. However,

in strong fluctuating conditions,

the probe tip should be fixed to the bottom

of the vessel with a special device.

Safe Coaxial Probe

You can fix the probe with the outer tube

to prevent the coaxial probe from shaking.

Funnel Type Flange

When the head height is more than

200 mm, the vessel wall will affect

the measurement. Use metal funnel

flange to reducee impact.

Large Diameter Head

1- Auxiliary signal plate with a

diameter of 100 to 150.

2- Auxiliary signal plate

3-Mounting head face and

auxiliary plate face must be

aligned.

Extension Rod and Boundary Ring

For long mount hood, extend the probe

or rope antenna so that it protrudes into

the vessel and fix it to prevent shaking.

Non-metal chamber mounting

1 Metal plate or metal flange

2 Non-metal vessel wall (plastic, glass or wood).

To ensure the reliability of the measurement ,

the guide radar level transmitter requires a metal

surface at the process connection. When mounted

in a non-metallic vessel such as a plastic vessel

or a glass vessel, use a flange and position a metal

plate under the process fitting. Make sure that the

plate is in direct contact with the process fitting.

Guide radar level transmitter tube recommendation:

For boat setup and turbulent conditions, the sensor should be mounted with a guide tube.

The material must be metal.

Constant diameter

Mark the polarization on the sensor.

Guide tube diameter should be larger than antenna diameter.

The diameter difference between the coaxial tube and the inside diameter of guide radar level transmitter tube is as small as possible.

Weld seam as smooth as possible and in line with the slit.

The slot width or hole diameter is less than or equal to 5 mm, it is smooth.

Length and number have no effect on the measurement.

The antenna diameter of the sensor should be suitable for the inner diameter of the pipe.

The inner wall of the guide wave tube should be straight and without a weld seam.

Since the sensor only measures the inner level of the tube, the waveguide tube should descend to the desired level.

Threaded Connection Mounting

The sleeve length should not be less than 100 mm.

The inner diameter of the sleeve must be at least 1 1/2'BSP

Dalga kýlavuzu tüpüne montaj

For boat setup and turbulent conditions, you can mount the sensor with the waveguide tube. For best measurement,

he diameter of the antenna should be close to the diameter of the waveguide tube.

What should a waveguide be like ?

-The material must be metal.

-The diameter must be constant.

-Polarization must be marked on the sensor.

-Waveguide tube diameter should be larger than antenna diameter.

-The diameter difference between the outer diameter of the radar antenna and the inner

diameter of the waveguide tube should be as small as possible.

-The source point should be as smooth as possible and on the same axis.

-Duct width or hole diameter less than or equal to 5 mm, without burrs. Length and number have no effect on the measurement.

-The antenna diameter of the sensor should be suitable for the inner diameter of the pipe.

-The inner wall of the guide wave tube should be smooth and there should be no welding seams.

-The guide tube length should not be more than the sensor antenna length.

Mixer Application;

Correct

If there is a mixer in the vessel where the sensor will measure the level,

the sensor should be mounted at a point away from the filling line and

as far as possible from the mixer that blocks the signals.

False signals reflected from the propellers of the mixer in the vessel

may reach the sensor and cause the sensor to make an incorrect evaluation.

In such cases, when the vessel is empty, erroneous signals must be detected

and false signal suppression must be applied. Thus, the sensor is prevented

from making incorrect measurements in case of faulty signals.

Installation Site Selection

Correct: Mount the sensor as far from the filling point as possible.

In terms of its lifetime, use protectors to keep it away from snow,

rain, sun and similar factors when necessary.

Wrong: Do not place the sensor on the fill line. The signal line

must see the surface to be measured.

CorrectWrong

By-Pass Application

If there are difficult physical factors such as mixer, ladder,

vessel reinforcement metals in the vessel where the sensor

will measure, By-Pass Application is required. In this way,

accurate and reliable measurement is provided .

Correct

Ø50mm rod antenna

For best measurement, the tip of the antenna should protrude

at least 15 mm outside of the vessel.
