Application Principle
1. Emitting radar beam
The radar level meter transmits microwave radar beam to the object through the antenna.
2. Interaction between beam and object
When the radar beam encounters the surface of an object, part of the beam energy will be reflected back. The reflected energy depends on the material, shape and surface characteristics of the object.
3. Detection of reflected wave time
The receiver records the time difference from transmitting the beam to receiving the reflected beam. This time difference is multiplied by the speed of light to obtain the distance between the radar beam and the target object.
4. Calculate the material level
Based on the reflection wave time, the radar level meter calculates the distance to the target object, which is the material level. Through data processing, the distance is converted into the actual material level value.
5. Display output results
Radar level meters are usually equipped with a display module or communication interface to display or output the level height value for users to read and further process.
Application Scenario
1. Industrial production
In the chemical, petroleum, food processing and other industries, radar level meters are often used to monitor the level of liquids or solids in containers such as storage tanks and tanks, helping to achieve accurate material management and production control.
2. Environmental monitoring
Radar level meters can be used to monitor water levels in reservoirs and rivers and sludge height in sewage treatment plants, providing data support for environmental monitoring and management.
3. Aerospace
In the fuel systems of aircraft, rockets and other aerospace vehicles, radar level meters are used to monitor the remaining amount and consumption of fuel in real time. In ground facilities at aerospace bases, it is used to monitor the storage of liquid and solid materials, such as chemicals, lubricants, and aviation kerosene.
4. Marine Engineering
In marine engineering, radar level meters can be used to measure the loading conditions of cargo in ship cargo holds and the level of liquid storage equipment on offshore platforms.
5. Urban construction
Radar level meters can be used to monitor the level of liquid or solid materials in municipal facilities, such as trash cans, water tanks, etc., which helps urban management and maintenance.
Ziasiot radar level meter
The radar level meter uses frequency modulated continuous wave (FMCW) technology. The antenna transmits a high-frequency frequency modulated radar signal, and the frequency of the radar signal increases linearly. The transmitted radar signal is reflected by the measured medium and received by the same antenna. 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 of the target to be measured is calculated based on this.
