The characteristics of radar level transmitter
1. Small antenna size, easy to install; Non-contact radar, no wear, no pollution.
2. Almost no corrosion, bubble effect; almost not affected by water vapor in the atmosphere, the temperature and pressure changes.
3. Serious dust environment on the high level meter work has little effect.
4. A shorter wavelength, the reflection of solid surface inclination is better.
5. Beam angle is small, the energy is concentrated, can enhance the ability of echo and to avoid interference.
6. The measuring range is smaller, for a measurement will yield good results.
7. High signal-to-noise ratio, the level fluctuation state can obtain better performance.
8. High frequency, measurement of solid and low dielectric constant of the best choice.
