The first is the single-rod type. The single-rod probe is a metal rod with a simple structure and is not easy to hang materials and scale.
It is suitable for liquid level measurement with high dielectric constant (relative dielectric constant 10~100) and medium viscosity (viscosity coefficient as low as cP). Such as general aqueous solutions, crude oil, hydrocarbons and other liquids. It can also be used for level measurement of powdery solids.
The second type is a cable-type probe. The probe is a flexible metal cable that can be bent.
The applicable scenarios are the same as the single-rod probe, but the magnetic wave propagation loss is slightly higher. In some cases where the measurement range is large, the single-rod probe can be replaced by a cable probe to facilitate transportation, installation and maintenance.
The third type is the double-rod probe, which consists of two parallel metal rods. The magnetic wave propagation loss of the double-rod probe is small, and it can still have a strong echo signal when measuring low dielectric constant media such as oil.
However, the double-rod probe is prone to material accumulation and scaling, causing false echoes and affecting the reliability of the measurement results. Therefore it is not suitable for measuring high viscosity liquids.
The fourth type is the dual-cable type. The dual-cable probe consists of two parallel flexible metal cables.
The electromagnetic wave propagation loss of the double-cable probe is smaller and the echo signal quality is better. But the dual cable probe is not suitable for measuring high viscosity liquids.
The last one is the coaxial type. The coaxial probe consists of a metal round tube and a metal thin rod. Its structure is similar to a coaxial cable, with electromagnetic waves propagating in the space between a metal round tube and a thin metal rod.
Compared with other types of probes, the energy loss is minimal and the echo signal quality is good. It can measure low dielectric constant liquids (relative dielectric constant 14~4.0) that cannot be measured by single-rod probes.
In addition, the coaxial guided wave radar level transmitter also has the characteristics of strong anti-interference ability and high reliability, and has been widely used.
However, due to the special structure of the coaxial probe, installation and maintenance are complicated, and it is not suitable for occasions with large measuring ranges. Because the space between them is limited, material accumulation and contamination are easy to occur, which affects the reliability of the measurement results, so it is not suitable for liquid level measurement of high-viscosity media.
The above five categories are the types of guided wave radar level transmitters classified according to the probe. Each has its advantages and limitations. So how to choose the one that is most suitable for you still depends on the working conditions of the medium being measured.

Radar Type Level Transmitters are essential in extreme environments where traditional level measurement solutions may fail to provide accurate and reliable readings. These advanced transmitters utilize radar technology to accurately measure levels of liquids, solids, or slurry in extreme conditions such as high temperatures, high pressures, corrosive materials, or harsh weather. Selecting the best radar type level transmitter for extreme environments requires careful consideration of various factors such as frequency range, antenna size, signal processing, and environmental conditions. In this article, we will explore the different types of radar level transmitters and discuss the key factors to consider when choosing the best transmitter for your specific application.
Understanding Radar Type Level Transmitters
Radar type level transmitters utilize electromagnetic waves to measure the distance or level of a substance within a tank or vessel. These waves are emitted by the transmitter's antenna and reflected off the surface of the substance, allowing the transmitter to calculate the distance or level based on the time taken for the signal to return. There are two main types of radar level transmitters: non-contact and guided wave radar. Non-contact radar transmitters are suitable for measuring liquids, slurries, and solids, while guided wave radar transmitters are best suited for measuring liquids and sludge. Understanding the differences between these two types of radar transmitters is crucial in selecting the best option for extreme environments.

Non-contact radar level transmitters use a high-frequency electromagnetic pulse to measure the time delay between the transmitted and reflected signals. This type of transmitter is ideal for extreme conditions where the substance being measured may have varying densities, temperatures, or pressures. Non-contact radar transmitters are also unaffected by changes in process conditions, making them suitable for applications in harsh environments. On the other hand, guided wave radar level transmitters use a probe that extends into the substance being measured, allowing for precise measurements in applications where non-contact transmitters may be impractical. Guided wave radar transmitters are particularly useful in extreme environments where the substance may have high dielectric properties or extreme temperatures.
Factors to Consider When Selecting Radar Type Level Transmitters for Extreme Environments
When choosing the best radar type level transmitter for extreme environments, it is crucial to consider several key factors to ensure accurate and reliable level measurements. These factors include the frequency range of the transmitter, the size and material of the antenna, the signal processing capabilities, and the environmental conditions in which the transmitter will be used. Understanding these factors will help you make an informed decision when selecting a radar level transmitter for your specific application in extreme environments.
The frequency range of a radar type level transmitter is an essential factor to consider when selecting the best option for extreme environments. Radar transmitters are available in various frequency ranges, each with its own advantages and limitations. Lower frequency transmitters are suitable for measuring substances with low dielectric properties, such as hydrocarbons, while higher frequency transmitters are ideal for measuring substances with high dielectric properties, such as water-based liquids. When selecting a radar level transmitter for extreme environments, it is important to consider the dielectric properties of the substance being measured and choose a frequency range that will provide accurate and reliable measurements in those conditions.
The size and material of the antenna are also critical factors to consider when selecting a radar type level transmitter for extreme environments. The antenna size determines the beam angle and focusing capabilities of the transmitter, which can impact the accuracy and reliability of level measurements. In extreme environments where the substance being measured may have varying densities or temperatures, it is essential to choose an antenna size that will provide a focused beam and accurate measurements. Additionally, the material of the antenna should be selected based on the corrosiveness of the substance and the environmental conditions in which the transmitter will be used. For example, in applications with corrosive materials or harsh weather, it is important to choose an antenna material that can withstand these conditions and provide long-term reliability.
Signal processing capabilities are another critical factor to consider when selecting radar type level transmitters for extreme environments. Advanced signal processing algorithms can enhance the accuracy and reliability of level measurements in extreme conditions, where the substance being measured may have varying densities or agitators that can cause signal distortion. When choosing a radar level transmitter for extreme environments, it is important to consider the signal processing capabilities and choose a transmitter with advanced algorithms that can compensate for these factors and provide accurate measurements.
Environmental conditions play a significant role in the selection of radar type level transmitters for extreme environments. In harsh weather conditions, high temperatures, high pressures, or corrosive environments, it is crucial to choose a transmitter that can withstand these conditions and provide reliable performance over the long term. It is important to consider the environmental ratings, material construction, and sealing mechanisms of the transmitter to ensure it can operate effectively in extreme conditions without compromising accuracy or reliability.
