26GHz NYRD-SD Radar Level Meter
Water drop type anticorrosive radar object level meter adopts microwave pulse measurement method, and can be normal in the range of industrial frequency band, low beam energy, can be installed in a variety of metal, non-metal containers or pipelines, non-contact continuous measurement of liquid, slurry and particle material object level. Applicable to the dust, change of temperature, pressure, and presence of inert gas and steam. Radar level meter has no harm to the human body and the environment, but also has the advantages of not being affected by the proportion of medium, not being affected by the change of dielectric constant, and not needing on-site adjustment. It is a very good choice whether for industrial needs, or for the consideration of economic benefits to customers.

The radar level meter antenna using PFA material,PFA plastic is a copolymer of a small amount of perfluoropropyl perfluorovinyl ether and polytetrafluoroethylene. The melting cohesiveness is enhanced and the viscosity of the solution is decreased, while the properties are unchanged compared with that of PTFE. The resin can be directly processed by ordinary thermoplastic molding. Suitable for making corrosion-resistant parts, wear resistant parts, sealing parts, insulating parts and medical instrument parts.
Radar Level Meter Measuring principle
The radar level antenna emits a narrow microwave pulse and transmits it down through the antenna. After the pulse touches the surface of the medium being measured, it is reflected back and accepted by the antenna system again, transmitting the signal to the electronic circuit part automatically converted into a object position signal(because the pulse propagation speed is extremely fast, The time it takes for electromagnetic waves to reach the target and reflect back to the receiver is almost instantaneous.)
Radar Level Meter Design features
- Water drop antenna is small in size and easy to install; Non-contact radar, no wear, no pollution.
- Resistant to corrosion, foam, water vapor, temperature and pressure changes.
- The beam Angle is small and the energy is concentrated, which enhances the echo ability and helps to avoid interference.
- The measurement blind area is smaller, and good results can be achieved for small tank measurement.
- High signal-to-noise ratio, even in the case of fluctuations can achieve better performance.
