KLD803 PTFE Anti-corrosion Radar Level Gauge with Small Blind Spot
Introduction
The KLD803 PTFE anti - corrosion radar level gauge is a state - of
- the - art device designed to meet the most demanding level
measurement requirements. It is engineered with PTFE material,
which endows it with outstanding anti - corrosion properties. This
enables the gauge to be used in harsh and corrosive environments
such as chemical storage tanks, wastewater treatment facilities,
and industrial processing plants where traditional materials would
quickly degrade.
One of the remarkable features of this radar level gauge is its
small blind spot. This means that it can provide highly accurate
and reliable measurements even in complex tank geometries or when
dealing with substances that have varying dielectric constants. The
small blind spot minimizes errors and ensures that the gauge can
detect the liquid or solid level with precision. It is easy to
install and configure, allowing for seamless integration into
existing process control systems, providing real - time level data
that is crucial for efficient operation and inventory management.
Feature
1. Continuous and accurate measurement
Due to the measurement characteristics of the radar level gauge, it
will not be affected by the environment, and has a wide range of
applications. It is non-contact measurement, does not contact the
surface of the medium, and can accurately and quickly measure
different media. The probe is hardly affected by temperature,
pressure, gas, etc.
2. It has the function of suppressing the interference echo
The interference echoes caused by joints and the noise of feeding
or discharging within the beam range of the radar level gauge can
be automatically suppressed by the internal fuzzy logic control.
3. Accurate and safe energy saving
The radar level gauge can measure under vacuum and pressure, and it
is accurate and safe. Can be without any restrictions, applicable
to various occasions. The chemical and mechanical properties of the
materials used in the radar level gauge are quite stable, and the
materials can be recycled, which is extremely environmentally
friendly.
4. No maintenance and strong operability
Almost undisturbed, no direct contact with the measuring medium, it
can be used in almost all kinds of occasions, such as vacuum
measurement, liquid level measurement or material level
measurement, etc. Due to the use of advanced materials, it is
durable to extremely complex chemical and physical conditions, and
it can provide accurate, operable, long-term stable analog or
digital level signals.
5. Easy maintenance and simple operation
The radar level gauge has fault alarm and self-diagnosis functions.
Analyze the fault according to the error code prompted by the
operation display module, determine the fault in time and eliminate
it, making maintenance and calibration more convenient and
accurate, and ensuring the normal operation of the instrument.
6. Wide range of applications, can measure almost all media
From the shape of the tank body, the radar level gauge can measure
the liquid level of spherical tanks, horizontal tanks, cylindrical
tanks, cylindrical cone tanks, etc.; from the tank function, it can
measure the liquid level of storage tanks and buffer tanks. ,
microwave tubes, and bypass tubes to measure the liquid level; from
the measured medium, it can measure liquid, particles, slurry, etc.

Installation Method
Flange installation
When using flange installation, the minimum distance between the
instrument and the tank
wall should be 200mm.
① datum plane
② vessel center or axis of symmetry
Hoisting Installation
Radar wave is a special form of electromagnetic wave. Radar level
gauge uses the special performance of electromagnetic wave to
detect material level. Electromagnetic waves can penetrate
interference sources such as space steam and dust, and are easily
reflected when encountering obstacles. The better the conductivity
of the measured medium or the greater the dielectric constant, the
better the reflection effect of the echo signal.
The higher the frequency of the radar wave, the smaller the launch
angle, the greater the energy (magnetic flux or field strength) per
unit area, the smaller the attenuation of the wave, and the better
the measurement effect of the radar level gauge.
Problems that should be paid attention to in installation
(1) When measuring liquid materials, the axis of the sensor is
perpendicular to the surface of the medium; when measuring solid
materials, the sensor should be inclined at a certain angle because
the solid medium has a stack angle.
(2) Avoid the feed port to avoid false reflections.
(3) The sensor should not be installed in the center of the arched
tank (otherwise the false echoes received by the sensor will be
enhanced), nor can it be installed very close to the tank wall, and
the installation position should be 1/2 of the radius of the tank.
(4) Avoid installing in places with strong eddy currents. For
example: due to stirring or strong chemical reaction, etc., it is
recommended to use waveguide or bypass tube for measurement.
(5) If the sensor is installed on the tube, the antenna must
protrude from the tube. The horn antenna protrudes at least 10mm
from the adapter. Rod antennas take over lengths up to 100 or
250mm. Take over the diameter of 250mm. The method of increasing
the diameter of the connecting pipe can be adopted to reduce the
interference echo generated by the connecting pipe.
