Choosing the Right Radar Level Sensors for Solids Materials.
When it comes to measuring the level of solid materials, there are many options available. But radar level sensors have become one of the most popular choices. This is due to their accuracy, reliability, and ability to measure the level of materials in various storage containers, including tanks and silos. However, with so many different radar level sensors on the market, it can be challenging to choose the right one for your specific needs. In this blog, we’ll explore the key factors to consider when selecting a radar level sensor for solid materials.
This is based on our many years of experience in level measurement. Hope this helps.
1. Operating Frequency
Radar level sensors use radio waves to measure the level of solid materials. And the frequency of these radio waves determines the accuracy and reliability of the measurement.
There are two main types of radar level sensors – pulse radar and frequency modulated continuous wave (FMCW) radar. Pulse radar operates at a higher frequency and provides more accurate measurements, but it is also more expensive. FMCW radar operates at a lower frequency and is less expensive, but it is less accurate.
When choosing a radar level sensor, consider the level of accuracy required for your application, as well as your budget.
Our most common ones are 6GHz-26GHz-80GHz-120GHz. You can refer to more 26GHz-80GHz-120GHz radar level meter parameter comparison. List of Radar Level Sensors
2. Material Properties
The properties of the solid material you are measuring will also impact your choice of radar level sensor.
The dielectric constant of the medium is also easy to be ignored, and attention should be paid to the medium with a small dielectric constant.
The problem of antenna hanging can not be ignored. Due to the strong adhesion of steam belt material and most mud, the radar level gauge will encounter the problem of antenna hanging.
The coating has no effect on the medium with small dielectric constant, but it will affect the medium with large dielectric constant. Influence of Dielectric Constant on Radar Level Meter
Introducing high-pressure wind to blow the antenna near the antenna can prevent material hanging. Some devices can be optionally equipped with a dust cover. At normal temperature, just cover the antenna with plastic film and clean the hanging material regularly.
Also, if the material is very dense or has a high moisture content. It can affect the accuracy of the measurement. If the material is very abrasive, it can wear down the sensor over time.
Consider the properties of the material you are measuring when choosing a radar level sensor.
The environment in which the radar level sensor will be installed can also impact its performance.
For example, if the sensor will be installed in an area with a lot of dust or steam. This can affect the accuracy of the measurement.
If the sensor will be installed in an area with high temperatures. Make sure the sensor is designed to operate in these conditions. Consider the environment in which the sensor will be installed when choosing a radar level sensor.
4. Storage Containers
The type of storage container in which the solid material is stored will also impact your choice of radar level sensor.
For example, if the container is very large, a long-range radar level sensor may be required. If the container is very tall, a high-level radar level sensor may be required.
Consider the size and shape of the storage container when choosing a radar level sensor.
The first is the range problem. When choosing a radar, there is often a misunderstanding, that is, the selected range should only be greater than the height of the tank. In fact, the range marked on the radar may be its maximum range.
The type selection also depends on the characteristics of the container. For example, whether the surface of the storage tank is smooth or corrugated, or even stirred.
The actual level that can be measured by the same radar level gauge is very different in different situations. For example, a certain liquid level gauge has a range of 30m. It is only a smooth surface liquid that can be measured to 30m. Once it is used in a non-stirred and rippled On the buffer tank, the result is different. When using it to measure the material level of more than ten meters of stirring, the low material level is often not measured. This is actually because the selection range is not enough. After increasing the range, the problem is solved.
5. Safety Considerations
Finally, safety considerations must also be taken into account when choosing a radar level sensor.
For example, if the material being measured is flammable, make sure the sensor is designed for use in hazardous areas.
If the material is toxic, make sure the sensor is designed to prevent contamination. Consider the safety requirements for your application when choosing a radar level sensor.

Usually level measurement media include water, slurry and powdery materials. The environment has a good static liquid level as well as a liquid level where a lot of vapor builds up. There are materials with severe dust and more steam environment. There is also pressure. There are also open ones. In short, all kinds of complications abound. So if you want to make good use of the radar level gauge and maximize its value, you must pay attention to these issues.
Choosing the right radar level sensor for solid materials requires consideration of several key factors. Including operating frequency, material properties, environment, storage container, and safety considerations. By taking these factors into account, you can choose a specific me radar level sensor that you needs and provides accurate and reliable measurements.
