Radar measurement: Measuring Principle

Micropilot works with high-frequency radar pulses which are emitted by an antenna and reflected from the medium surface due to a change of the dc value (relative dielectric constant). The Time-of-Flight of the reflected radar pulse is directly proportional to the distance traveled. If the tank geometry is known, the level can be calculated from this variable.

Benefits

  • Non-contact, maintenance-free measurement
  • Unaffected by medium properties like density and conductivity, in bulk solids also
  • Unaffected by filling noise and dust
  • Freely adjustable measuring range
  • For high temperatures up to +450°C/+842°F
