    **A purging system installed between the flange and the horn antenna is an option for the SITRANS LR 400. The system provides an inlet on the flange where cooling air or cleaning fluid passes through the flange and exits the inside of the horn to clean it. The customer will supply the purging medium by manual or automatic valve system.

  • Page 25: Operation

    Measuring Principle The SITRANS LR 400 operates according to the FMCW (Frequency Modulated Continuous Wave) method. Its antenna sends microwaves to the surface of the measuring medium, the frequency of which is modulated continuously (see Determining the Differential Frequency on page 22).

  • Page 26

    Every reflection at a surface generates a different frequency. The reception signal therefore consists of a frequency mix from which the disturbance frequencies must be filtered. These can be caused by fixed targets such as struts inside the vessel. Page 22 SITRANS LR 400 – INSTRUCTION MANUAL 7ML19985FH03...
