Basics of Guided Wave Radar measurement

Radar Technology works on the principle of time of flight for radio waves to travel from point of emissions and receiving back.

Their are two basic type of Radar Technology prevalent in industry.

  1. Non contact type:- Radar level measurement

  2. Contact type:- Guided Wave Radar Level measurement

The difference between both of these is only that in guided wave radar level measurement a guide is provided through which radio waves travel and and reflect back.

Guided Wave Radar measurement have following advantages over counterpart radar level measurement.

  • Can work for liquids with low dielectric constant

  • Narrow beam width

  • Foaming Application

  • Two Dielectric medium

  • With different dielectric values

  • Not effected by change in product property like Temperature , pressure or density etc
