High-Frequency Radar Level Gauges: The Preferred Choice For Bulk Material Measurement in Power Plants

It is well known that power plants face challenges in level measurement for coal silos, limestone silos, ash storage, and desulfurization systems. High-frequency radar level gauges excel in bulk material measurement due to their high energy, narrow beam angle, small antenna size, and high precision, ensuring accuracy and safety.

 

 

In bulk material measurement, the reflection of radar waves primarily relies on the diffuse reflection from the material surface, with intensity proportional to the particle size and inversely proportional to the wavelength. Since the diameter of most bulk materials is typically less than 50mm, high-frequency radar becomes the preferred choice for measuring bulk materials.

High-frequency radar level gauges utilize advanced echo and data processing technologies, and their high-frequency radar waves possess excellent penetration capabilities. Consequently, they outperform contact and other non-Contact level measurement.The advantages of high-frequency radar level gauges include:

1.Continuous and Stable Measurement: As there is no direct contact with the medium, they are minimally affected by temperature, pressure, and gas.

2.Strong Anti-Interference Ability: Internal fuzzy logic control can automatically suppress interference echoes caused by joints, feeding, or discharging.

3.False Echo Recognition Function: The system can automatically identify and exclude interference from false echoes, ensuring measurement accuracy.

4.Simple Parameter Setting: Parameters can be easily set via the operation keys on the level gauge or remotely using a PC with HART protocol and dedicated software.

5.Safe, Efficient, and Environmentally Friendly: Even under vacuum or pressurized conditions, high-frequency radar level gauges can measure accurately, offering high reliability suitable for various environments.

6.Easy Installation: Radar level gauges can be directly installed on the top of storage tanks, adaptable to various industry applications.

7.Minimal Maintenance Required: Microwave signals exhibit strong resistance to interference, making them suitable for complex chemical and physical conditions, providing long-term stable analog or digital level signals.

8.Easy Maintenance and Operation: Equipped with fault alarm and self-diagnostic functions, they can quickly locate faults and perform repairs, ensuring normal operation of the instrument.

These advantages make high-frequency radar level gauges stand out in many applications, providing users with reliable solutions.
