Radar Level Gauges Measurement Technology
The general principle of the FM continuous wave radar level gauge is that the radar emits electromagnetic waves on the top of the tank, and the electromagnetic waves are received by the radar after being reflected by the medium.
The frequency difference δf between the received signal and the transmitted signal is proportional to the distance R from the surface of the medium: R=C (speed)*δf (frequency difference)/2/K (frequency modulation slope).
Because the speed of light C and the frequency modulation slope K are known, the frequency difference δf can be estimated to obtain the distance R from the radar installation position to the material surface. And then through the known total height of the tank, subtract the spatial distance from the radar to the material surface (referred to as Empty height) to get the height of the material level.
Advantages of Using Radar Level Gauges
- Millimeter-wave radar, with a measurement accuracy of up to ±1mm, and a minimum blind area of 0.1m.
- The smaller antenna size satisfies the measurement of more working conditions.
- A variety of lens antennas, smaller launch angle, more concentrated energy, stronger echo signal, under the same industrial and mining conditions, compared to
Other radar products have higher reliability. - With stronger penetrability, it can be used normally even if there is adhesion and condensation.
- The dynamic signal range is larger, and the measurement of low dielectric constant medium is more stable.
- 6. A variety of measurement modes, the radar reaction time in the fast measurement mode is less than 1S.

FAQ
A radar level gauge is an instrument used in various industries to measure the level of materials without making physical contact. It utilizes radar wave technology, emitting waves that bounce off the material surface and return to the gauge, enabling it to calculate the material’s level accurately.
Radar level measurement is known for its exceptional accuracy. While the exact degree of accuracy can vary depending on the specific model and operating conditions, most radar level gauges can achieve accuracy within a few millimeters.
There are mainly two types of radar level gauges: guided wave radar (GWR) and non-contact (or free-space) radar. GWR uses a probe to guide the radar waves to the material surface, while non-contact radar emits waves freely towards the material. Each type has its unique advantages and is suitable for different applications.
A radar level meter works by emitting radar waves towards the surface of the material being measured. These waves bounce back off the surface and are captured by the meter. By calculating the time it takes for the waves to travel to the surface and back, the meter can determine the level of the material accurately.
In conclusion, radar level gauges are a sophisticated and highly reliable tool for non-contact level measurement across diverse industries.
At Sino-Inst, we understand the vital role that accurate level measurement plays in your operations. We’re an experienced manufacturer and supplier of radar level gauges.

Difference Between Radar and Guided Wave Radar Level Transmitter
Difference parameter Between Radar and Guided Wave Radar Level Transmitter
First of all, you can learn about the detailed technical parameters, advantages and disadvantages, working principles, etc. of radar level transmitters and guided wave radar level transmitters from our product page.
Different ways of contact
Radar Level Transmitter is non-contact, and Guided Wave Radar Level Transmitter is contact.
In other words, GWR cannot be used in situations where food grade requirements are higher.
Different working conditions and media
- Radar Level Transmitter has a wide range of applications and can measure almost all media;
- From the shape of the tank body, the radar level gauge can measure the liquid level of spherical tanks, horizontal tanks, cylindrical tanks, cylindrical cone tanks, etc.;
- In terms of tank function, it can measure the liquid level in storage tanks, buffer tanks, microwave pipes, and bypass pipes;
- In terms of the measured medium, liquids, particles, slurries, etc. can be measured.
Guided Wave Radar Level Transmitter needs to consider the corrosiveness and adhesion of the medium, and it is more difficult to install and maintain a guided wave radar that is too long.
- Guided Wave Radar Level Transmitter has strong ability to suppress steam and foam, and the measurement will not be affected;
- It is not affected by the density of liquid, the looseness of solid materials, temperature, and dust during feeding;
- Low maintenance, high performance, high precision, high reliability and long service life.
Regarding different media situations, I think “Doug Anderson VEGA Controls Ltd” summarized it very well. It’s available for everyone’s reference. Here we quote it:
Different product selections
Common Radar Level Transmitter can be used interchangeably.
The Guided Wave Radar Level Transmitter generally cannot be used interchangeably because the length of the waveguide rod (cable) is fixed according to the original working conditions. Affected by this, the selection of guided wave radar is more troublesome than that of ordinary radar.
Different measuring ranges
Ordinary Radar Level Transmitter is commonly used on tanks of 30 and 40 meters, and can even measure up to 150 meters.
The guided wave radar Level Transmitter can measure up to 30m.
Guided Wave Radar Level Transmitter also needs to consider the force of the waveguide rod (cable). Due to the force, the measurement distance of guided wave radar is generally not very long.
However, in some special working conditions, the Guided Wave Radar Level Transmitter has obvious advantages. For example, there is stirring in the tank and the medium fluctuates greatly. In such working conditions, the measured value of the guided wave radar with a fixed bottom is more stable than that of the flexible radar.
There is also material level measurement in small tanks. Due to the small installation and measurement space (or there are many interference objects in the tank), ordinary Radar Level Transmitter is not suitable. At this time, the advantages of guided wave radar appear.
