Product advantage:
● Small antenna size, easy to install; Non - contact radar, no wear, no pollution. Almost free from corrosion and foam; Almost unaffected by changes in water vapour, temperature and pressure in the atmosphere.
● Severe dust environment has little influence on the work of high frequency level meter.
● Shorter wavelength, better reflection on tilted solid surfaces. Small beam Angle, concentrated energy, enhance the ability of echo and avoid interference at the same time. ● Measurement blind area is smaller, for small pot measurement will also achieve good results.
● High signal-to-noise ratio, even in the case of fluctuation can get better performance.
● High frequency, is the measurement of solid and low dielectric constant medium choice.
