Technical Characteristics And Scope Of Application Of Guided Wave Radar Level Gauge

Guided wave radar level gauge is a kind of microwave level gauge, which is an application of microwave (radar) positioning technology. It transmits energy waves through a device that can emit energy waves (usually pulse signals), the energy waves are transmitted in the waveguide, the energy waves are reflected by obstacles, and the reflected energy waves are transmitted from the waveguide to the receiving device, and then by The receiving device receives the reflected signal. The change of material level is determined according to the time difference of the energy wave movement process. The microwave signal is processed by the electronic device, and finally converted into an electrical signal related to the material level.
The energy radiation level is low, and the energy wave used by the device is a pulsed energy wave (the frequency is generally lower than that of the smart radar level gauge). Generally, the maximum pulse energy of the pulse energy wave is about 1mW (the average power is about 1μW), which will not cause radiation damage to other equipment and personnel.
Scope of application:
The guided wave microwave level meter is used for continuous contact measurement of liquids, slurries and granular materials and other media with relatively small dielectric constants. It is suitable for occasions with large temperature and pressure changes and the presence of inert gases or steam.
Has the following characteristics:
1. Strong versatility: it can be used to continuously measure the level of liquid and solid powder, granular material and liquid;
Cable probe: mainly used to measure liquid and solid material level, the maximum measuring distance is 35 meters;
Rod probe: mainly used for liquid;
Coaxial rod probe: for liquids;
It can also be used in harsh occasions such as corrosion and impact; it can provide signal interfaces such as HART, 4...20Ma, PROFIBUS-PA, and Foundation Fieldbus to the system;
2. Anti-hanging material: The unique circuit design and sensor structure make its measurement not affected by the sensor's hanging material, and it does not need to be cleaned regularly to avoid mismeasurement.
3. Maintenance-free: There are no moving parts during the measurement process, and there is no problem of damage to mechanical parts, and no maintenance is required.
4. Anti-interference: contact measurement, strong anti-interference ability, can overcome the influence of steam, foam and stirring on the measurement.
5. Accurate and reliable: the measurement quantity is diversified, which makes the measurement more accurate, and the measurement is not affected by environmental changes, with high stability and long service life.
In addition: probe rods and probe cables can be replaced; HART or PROFIBUS-PA communication protocol and FOUNDATION fieldbus protocol, easy calibration, easy on-site calibration operation through digital liquid crystal display, simple configuration setting and programming through software.
