Description

Technical Field

[0001] The utility model relates to the technical field of liquid level meter measurement, in particular to a radar liquid level meter using a high-frequency radar component. Background Art

[0002] Radar level meter is an advanced tool for level measurement based on radar principle. It uses high-frequency radar beam to accurately determine the height or depth of liquid or material by emitting microwave pulses and receiving reflected signals. This measurement method has the advantages of non-contact, high precision and real-time performance, so it has been widely used in various industrial fields. The core components of radar level meter include high-frequency radar transceiver, antenna and signal processing unit. High-frequency radar transceiver is responsible for generating and transmitting microwave pulses, and the antenna sends microwave pulses to the measured object in a direction and receives the reflected signal. The signal processing unit processes and analyzes the received signal to obtain information on the height or depth of the liquid level. Radar level meter has a large measurement range, usually up to tens of meters, and the measurement range can be adjusted according to actual needs. In addition, it has good stability and reliability, and can maintain high measurement accuracy even in harsh environmental conditions, which makes radar level meter particularly suitable for level measurement needs in petrochemical, food processing, water treatment, pharmaceutical and other industries.

[0003] A radar level meter using a high-frequency radar component with a public number of CN209131786U is characterized in that it includes a housing, a high-frequency radar component, an adapter, a flange and an antenna. The high-frequency radar component is fixedly installed inside the housing, and the lower surface of the housing is connected to the antenna through an adapter. A flange is fixedly arranged on the outer side of the adapter. The high-frequency radar component includes a housing, a tube shell, a wave-transmitting cover, a shell cover, a pulse generator, a PCB board and a waveguide. The housing is connected to the shell cover, and a tube shell is arranged at one end of the housing. The tube shell is a cylindrical hollow tube structure, and a wave-transmitting cover is arranged at one end of the tube shell away from the housing. A pulse generator and a PCB board are fixedly installed inside the shell, the pulse generator is connected to the PCB board, a waveguide is fixedly arranged inside the tube shell, and the waveguide is connected to the pulse generator. The utility model has a reasonable structure and greatly improves the sealing performance compared with the traditional sealing performance, which reduces the probability of failure of the high-frequency radar component. In this scheme, when installing the radar liquid level meter, professional staff are required to install it, the installation efficiency is low, and it is easy to be misplaced and tilted, which affects the later measurement and stability. For this reason, we propose a radar liquid level meter using high-frequency radar components. Utility Model Content
