Description:

Industrial type radar liquid level meter with RS 485

  Microwave emited by guided wave radar transmit through detecting element( steel rod or steel cable) and encounter the measured medium,owing to the bielectric constant change suddenly,the microwave occur changed shape that result in reflection,parts of pulse energy are reflected.transmission pulse and echo pulse time interval are proportional to measured medium.

  Radar level transmitter antenna microwave pulse is narrow, the downward transmission antenna. Microwave exposure to the medium surface is reflected back again by the antenna system receives, sends the signal to the electronic circuit automatically converted into level signals (because the microwave propagation speed, electromagnetic wave to reach the target and the reflected back to the receiver this time is almost instantaneous)

  Through the electronic components to run time into level signals. Measurement of this special time extension method can realize stable, accurate in a very short period of time.Even if the condition is very complex, the presence of false echo, with the latest micro-processing technology and debugging software also can analyze the level echo accurately.

Characteristics  :

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.
