Radar substance level gauge
Category： Level transmitter
Product Details
Radar sensors for all liquid measurement applications
Radar level measuring instrument with 80GHz frequency. Radar beams have unique focusing capabilities. Compared with 26G or 6G radar, it has the characteristics of higher frequency, shorter wavelength, smaller beam angle and more concentrated energy. Even in containers with built-in components, such as heating coils or stirring devices, the sensor provides reliable measurement results, and the attachment on the inner wall of the container does not affect the accurate measurement results.
The larger the dynamic range of a radar sensor, the wider its application range and the higher its measurement reliability. In this regard, 80GHz occupies a leading position in the market. Compared to radar sensors hitherto, it is clearly better able to measure poorly reflective media. It can measure the liquid level even when it is very close to the bottom of the container. Even in the presence of foam, extreme vibrations on the surface of the medium, the presence of condensate or the presence of attachments on the antenna, it can be measured safely and reliably.
Having the smallest antenna in its type is a great advantage when used in small tanks or process vessels. Therefore, it can be used in different industrial fields and more different occasions.

80GHz FM Radar Level Meter
Principle
The 80G radar level gauge adopts frequency modulated continuous wave (FMCW) technology. The antenna emits a Gauton's 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 transmitting signal frequency and the receiving signal frequency is proportional to the measured distance. The frequency difference signal is collected, and the spectrum of the reflected echo is obtained by fast Fourier transform (FFT), and the distance to be measured is calculated.
Features
Compared with 26G or 6G radar, 80G radar has the characteristics of higher frequency, shorter wavelength, smaller beam angle and more concentrated energy. With the application of FMCW technology, 80G radar has the following characteristics:
- Large range, small blind area
- The beam angle is small, the antenna size is small, and it is easy to install. Small impact of obstacles due to tank nozzle size
- High measurement accuracy, strong anti-interference ability and high reliability.
Application
Refitting on existing equipment is simple and does not require modification.

guided wave radar level meter
Principle
Guided wave radar level gauge is a ranging system based on the principle of time travel. The instrument probe sends out a 1GHz micro-power electromagnetic wave signal along the detection component (probe rod or detection cable) to propagate at the speed of light. When the battery wave contacts the surface of the measured substance, the electromagnetic wave is reflected back due to the sudden change of dielectric constant. The reflected electromagnetic wave propagates along the probe assembly and returns to the meter probe. The time interval between the emission and reception of the electromagnetic wave is proportional to the distance from the instrument probe to the measured medium, so that the distance from the instrument probe to the surface of the measured medium can be calculated.
Input
The reflected pulse signal is transmitted to the electronic circuit part of the instrument along the cable or rod probe, and the microprocessor processes the signal to identify the echo generated by the microwave pulse on the surface of the material. The correct echo signal recognition is completed by intelligent software, and the distance D from the surface of the material is proportional to the time travel T of the pulse:
D = C×T/2 where C is the speed of light
Since the distance E of the empty tank is known, the level L is: L = E-D
Output
By inputting empty tank height E(= zero point), full tank height F(= full scale) and some application parameters, the application parameters will automatically adapt the instrument to the measurement environment. Corresponds to 4... 20mA output.
Measurement range
F-measurement range
E ---- empty tank distance
B- --- Top blind area
H ---- minimum distance from the probe to the tank wall
The top blind area is between the highest material level of the material and the measurement reference point.
The minimum distance.
The bottom blind area refers to the area near the bottom of the cable that cannot be accurately measured.
A distance.
Between the top blind area and the bottom blind area is the effective measurement distance.
Note: Only when the material is between the top blind area and the bottom blind area, can the reliable measurement of the level in the tank be guaranteed.
