Datum measurement: Screw thread bottom or the sealing surface of the flange.

Note: Make sure the radar level meter the highest level cannot enter the measuring blind area (Figure D shown below).

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