Introduction

Radar level transmitters are widely used in various industries to measure the level of liquids, solids, or slurry in tanks or vessels. There are two main types of radar level transmitters: non-guided radar level transmitters and guided radar level transmitters. Both types have their own set of attributes and advantages, which make them suitable for different applications.

Non-Guided Radar Level Transmitter

Non-guided radar level transmitters, also known as free-space radar level transmitters, use radar waves to measure the distance from the transmitter to the surface of the material being measured. These transmitters are ideal for applications where there is no need for a stilling well or nozzle, as they can measure the level of the material directly without any physical contact. Non-guided radar level transmitters are also suitable for measuring levels of corrosive or abrasive materials, as they do not come into direct contact with the material.

One of the key attributes of non-guided radar level transmitters is their ability to provide accurate and reliable measurements even in harsh environmental conditions. These transmitters can withstand extreme temperatures, pressures, and vibrations, making them suitable for use in challenging industrial environments. Non-guided radar level transmitters are also easy to install and require minimal maintenance, which helps to reduce downtime and operational costs.

Another advantage of non-guided radar level transmitters is their versatility. These transmitters can be used to measure the level of a wide range of materials, including liquids, solids, and slurry. They are also suitable for use in tanks or vessels of various shapes and sizes, making them a flexible and cost-effective solution for many different applications.

In addition, non-guided radar level transmitters offer high accuracy and precision in level measurement. They can provide real-time data on the level of the material being measured, allowing for better control and monitoring of industrial processes. Non-guided radar level transmitters are also immune to changes in temperature, pressure, or density of the material, ensuring consistent and reliable measurements over time.

Overall, non-guided radar level transmitters are a reliable and versatile solution for measuring the level of liquids, solids, or slurry in industrial tanks or vessels. Their ability to provide accurate measurements in harsh environmental conditions, along with their ease of installation and low maintenance requirements, make them a popular choice for many different applications.

Guided Radar Level Transmitter

Guided radar level transmitters, also known as guided wave radar level transmitters, use a probe or rod to guide the radar waves to the surface of the material being measured. These transmitters are ideal for applications where there are obstructions or vapors that could interfere with the radar signal, as the guided wave can bypass these obstacles and provide accurate measurements. Guided radar level transmitters are also suitable for measuring the level of materials with low dielectric constants, such as oil or foam.

One of the key attributes of guided radar level transmitters is their ability to provide accurate and reliable measurements in challenging process conditions. These transmitters can measure the level of materials with high accuracy, even in applications with extreme temperatures, pressures, or densities. Guided radar level transmitters are also suitable for use in tanks or vessels with agitators or other moving parts, as the guided wave can avoid interference from these obstacles.

Another advantage of guided radar level transmitters is their ability to provide continuous level measurement, even in applications with changing process conditions. These transmitters can provide real-time data on the level of the material being measured, allowing for better control and optimization of industrial processes. Guided radar level transmitters are also immune to changes in temperature, pressure, or density of the material, ensuring consistent and reliable measurements over time.

In addition, guided radar level transmitters offer high accuracy and precision in level measurement. They can provide accurate measurements of the level of liquids, solids, or slurry, even in applications with challenging process conditions. Guided radar level transmitters are also easy to install and require minimal maintenance, which helps to reduce downtime and operational costs.

Overall, guided radar level transmitters are a reliable and accurate solution for measuring the level of liquids, solids, or slurry in industrial tanks or vessels. Their ability to provide continuous level measurement in challenging process conditions, along with their high accuracy and precision, make them a popular choice for many different applications.

Conclusion

Non-guided radar level transmitters and guided radar level transmitters both have their own set of attributes and advantages, which make them suitable for different applications. Non-guided radar level transmitters are ideal for applications where there is no need for a stilling well or nozzle, while guided radar level transmitters are suitable for applications with obstructions or vapors that could interfere with the radar signal. Both types of transmitters offer high accuracy and reliability in level measurement, making them popular choices for measuring the level of liquids, solids, or slurry in industrial tanks or vessels.
