1 Measurement principle
The principle of the frequency modulated continuous wave radar
level meter is that the radar emits electromagnetic waves on the
top of the tank, and the electromagnetic waves are received by the
radar after being reflected by the medium. The frequency difference
δf between the received signal and the transmitted signal is
proportional to the distance R to the surface of the medium: R = C
(speed) * δf (frequency difference) / 2 / K (frequency modulation
slope). Because the speed of light C and the frequency modulation
slope K are known, the frequency difference δf can be calculated to
obtain the distance R from the radar installation position to the
material surface. Then, the known total height of the tank is
subtracted from the spatial distance from the radar to the material
surface (referred to as the empty height) to obtain the height of
the material level.
2 Product Features
1. The measurement accuracy of millimeter wave radar can reach
±1mm, and the measurement blind area is 10-50mm.
2. Smaller antenna size to meet the measurement of more working
conditions.
3. A variety of lens antennas, 3° emission angle, more concentrated
energy, stronger echo signal, higher reliability than other radar
products under the same industrial and mining conditions.
4. It has stronger penetration and can be used normally even in the
presence of adhesion and condensation.
