。Non-contact measurement, no wear and tear, and no pollution.
。Small antenna size, easy to install. 
。The measurement blind spot is small, therefore particularly effective on the measurement of small storage tanks. 
。The beam angle is small, the energy is concentrated, and the echo ability is enhanced, making it conducive in avoiding interfering objects. 
。Unaffected by corrosion, foam, and viscosity.
。Unaffected by changes in water vapor, temperature and pressure in the atmosphere.
。High signal-to-noise ratio, even in the case of fluctuations.
。The 80GHz frequency is the best choice for measuring low dielectric constant media, and it is suitable for measuring material working conditions with dielectric constant ≥ 1.8 of the medium under test.
