Table 2 : Model Selection 

Remark: If you require process connection in flange type, please indicate flange standard before order.

(1) Based on self-aeveloped milimeter-wave radio frequency chip to achieve a more compact radio frequency architecture.
(2) Higher signal-to-noise ratio, almost unaffected by level fluctuations.
(3) The measurement accuracy is millimeter-level accuracy (1mm), which can be used for metrology-level measurement.
(4) The measurement blind area is small, and the effect of measuring the liguid eve of small storage tanks is better.
(5) The beam angle can reach 3 and the energy is more focused,effectively avoiding false echo interference.
(6) High frequency signal, can effectively measure the level of medium with low dielectric constant (e>1.5).
(7) The antenna adopts PTFE lens, which is effective anti-corrosion and anti-hanging material.
