Measuring principle

Guided radar works with high-frequency radar pulses which are guided along a probe. As the pluses impact the medium surface, the characteristic impedance changes and part of the emitted pulse is reflected. The time between pulse launching and receiving is measured and analyzed by the instrument and constitutes a direct measure for the distance between the process connection and the product surface.

FM radar works with high-frequency radar pulses which are emitted by an antenna and reflected from the product surface. The time of flight of the reflected radar pulse is directly proportionate to the distance traveled. If the tank geometry is known, the level can be calculated from this variable.

Application guidelines
.level, volume measurement
.liquids, powders and granular mediums with Er>1.4
.medium with turbulent surface, dense dust, vapour or pressurized gas layers above the product surface
.For all tank shapes, for narrow vessels
.Heavy industrial applications

 

Product list
  • MONITOR Guided Wave Radar solid transmitter

    MONITOR four-wire guided wave radar level gauge is based on the principle of Time Domain Reflectometry (TDRT im eDomain Reflectometry) based radar level meter, time domain reflectometer principle first is used for communication cable fault detection, and today we will be their (radar level meter) successfully used in industrial measurement.
