80G Radar Level Gauge For Slightly Corrosive Liquid KLD802
Introduction
KLD800 series 80G radar level gauge adopts frequency modulated
continuous wave (FMCW) technology. The antenna emits a
high-frequency FM radar signal, and the frequency of the radar
signal increases linearly. The transmitted radar signal is received
by the same antenna after being reflected by the measured medium.
At the same time, the frequency difference between the transmitted
signal frequency and the received signal frequency is proportional
to the measured distance. The collected frequency difference signal
is subjected to fast Fourier transform (FFT) to obtain the spectrum
of the reflected echo, and the distance to the target to be
measured is calculated based on this.
Feature
⚫ Millimeter wave radar, the measurement accuracy can reach up to
±2mm, and the minimum measurement blind zone is 0.05m.
⚫ The smaller antenna size satisfies the measurement of more
working conditions.
⚫ A variety of lens antennas, smaller launch angles, more
concentrated energy, stronger echo signals, and higher reliability
than other radar products under the same industrial and mining
conditions.
⚫ It has stronger penetration and can be used normally in the case
of adhesion and condensation.
⚫ The dynamic signal range is larger, and the measurement of low
dielectric constant media is more stable.
⚫ Multiple measurement modes, radar response in fast measurement

Installation
1.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
2.Hoisting Installation
Installation Requirements
When installing the instrument, avoid installing it above the
material inlet, and try to avoid various objects that affect the
signal, such as stirring paddles, etc.
Under extremely complex working conditions, the instrument can work
normally if there is no obstacle in the area with a radius of 20cm
centered on the installation point.
Installation connection diagram:
The maximum installation spool height H max depends on the
installation spool diameter D and the size of the product launch
angle.
Too long installation connection will affect the radar performance.
