The reason why radar level gauge can measure accurately

Radar level gauge In addition, the frequency of radio wave is high and the working ability is strong. Even if the solid hopper has large height width ratio, small diameter and strong smoke and dust, the radar level meter can also show continuous, reliable and stable accurate measurement results.
Among them, the sensor of dcrd1000a series products is a 26G high frequency radar detection level measuring instrument panel, which has the following accurate measurement characteristics:
High frequency accurate measurement of solid and low relative permittivity materials has a significant advantage: non-contact Radar level gauge No damage, no pollution
The small size of wireless antenna is conducive to installation, shorter light wavelength, stronger reflection surface on the skew solid surface layer, smaller blind spot for accurate measurement, and good practical effect can be obtained for accurate measurement of small tank.
The beam angle is small and the kinetic energy is concentrated, which improves the radar echo working ability. In addition, it is beneficial to avoid the influence objects and is hardly damaged by the etched foam plastics.
High frequency stability, even in ups and downs, can also get better characteristics, almost free from water vapor, temperature and working pressure changes in the air.
More serious smoke and dust, natural environment is not easy to harm the radio wave work of this product series, each has a different specification of wireless antenna, wireless antenna specifications are not the same, radar level meter beam angle is not the same. Let's discuss the delivery perspective of dcrd1000a product series.

Dcrd1000a1: wireless antenna specification, transmitting angle - φ 46mm, 20 °, - φ 75mm, 15 °
Dcrd1000a2: wireless antenna specification, transmission angle: - φ 46mm, 18 °, - φ 76mm, 12 °, - φ 96mm, 8 °
Dcrd1000a3: wireless antenna specification, transmitting angle - φ 76mm, 12 °; - φ 96mm, 8 °; - φ 12mm, 6 °
Dcrd1000a4: wireless antenna specification, transmission angle: - φ 196mm, 5 °; - φ 243mm, 4 °
Dcrd1000a6: wireless antenna specification, transmission angle: - φ 75mm, 12 °; - φ 144MM, 8 °
The width of the radio wave is not the same as the width of the radio wave. Formula conversion:
W = Tan (beam angle / 2) x measurement range x2
This is it. Radar level gauge The reason why it can be measured accurately.
