Transmitters & Indicators
  Pulse Radar 138C/K
An extremely narrow microwave pulse is emitted by the antenna of radar level instrument which travels at the speed of light. A part of its energy is reflected by the surface of measured medium & is received by the antenna. The time taken by emitted pulse to travel from antenna & the reflected pulse back to the antenna is proportional to the distance between the reference point of antenna and the measured medium . As the electromagnetic wave is transmitted at an extremely high speed, the time lapse is very small and is in nanoseconds. It is very difficult to indentify such small time lapse. 138 series of Pulse Radar has adopted a special demodulation technology which enables to detect the time taken between pulse emission and reception correctly. This results in accurate level measurement.
