Flow Meter
Radar Level Meter
Introduction
Frequency modulated continuous wave (FMCW) is adopted for radar level instrument (80G). The antenna transmits the high frequency and frequency modulated radar signal.
The frequency of the radar signal linearly increases. the transmitted radar signal is reflected by dielectric to be measured and received by antenna. at the same time, the difference between the frequency of transmitted signal and that of the received signal is proportional to the measured distance.
Therefore, the distance is calculated by the spectrum derived from the analog-to-digital conversion frequency difference and the fast fourier transform (FFT)

Advantages
(1) Based on self-aeveloped milimeter-wave radio frequency chip to achieve a more compact radio frequency architecture.
(2) Higher signal-to-noise ratio, almost unaffected by level fluctuations.
(3) The measurement accuracy is millimeter-level accuracy (1mm), which can be used for metrology-level measurement.
(4) The measurement blind area is small, and the effect of measuring the liguid eve of small storage tanks is better.
(5) The beam angle can reach 3 and the energy is more focused,effectively avoiding false echo interference.
(6) High frequency signal, can effectively measure the level of medium with low dielectric constant (e>1.5).
(7) The antenna adopts PTFE lens, which is effective anti-corrosion and anti-hanging material.

Application
Measure the level of solid particles, chemical liquid tank, oil tank and process containers.
1.Radar level meter is working based on electromagnetic wave. So it could have max 120m measure range.
2.Compared with other type level meter, 80G radar level meter could measure different kinds of oil, chemical liquids, solid powder,and many other mediums.
3. 80G radar level meter could work in harsh working condition. It won’t be affected by temperature, pressure and humidity. With PTFE horn, it even could work in corrosive condition, such as acid liquid.
4.Customer also could choose different connection methods, such as flange, thread, bracket.
