    Transmitter overview 2.1  Measurement principle The Rosemount 5408 is a two-wire transmitter for continuous level measurements using fast-sweep Frequency Modulated Continuous Wave (FMCW) technology. The transmitter continuously emits signal sweeps with a constantly varying frequency towards the product surface. Since the transmitter continuously changes the frequency of...
  • Page 10 Transmitter overview Reference Manual March 2023 00809-0100-4408 transmitter may be mounted in a still pipe. In addition, measurement performance can be optimized by configuring the appropriate process conditions settings. Measurement in foamy applications depends largely on the foam properties. When the foam is light and airy, the actual product level is measured.

  • Page 11: Vessel Characteristics

    2.4  Application examples The Rosemount 5408 and 5408:SIS are ideal for level measurements over a broad range of liquid and solids applications. The transmitters are virtually unaffected by changing density, temperature, pressure, media dielectric, pH, and viscosity. Non-contacting radar level is ideal for harsh conditions such as corrosive and sticky media, or when internal tank obstructions are a limiting factor.
  • Page 12 Blenders and mixers The Rosemount 5408 can help you withstand the rigors of blenders and mixing tanks. Easy to install and commission, it is also unaffected by virtually any fluid property change. Open atmospheric applications The Rosemount 5408 measures reliably in open applications, from short range sumps or ponds to long range dams.

  • Page 13: Components Of The Transmitter

    March 2023 Still pipe and chamber installations The Rosemount 5408 is a great choice for level measurement in tanks with small diameter still pipes. It may also be used in chambers, but guided wave radar is generally the best fit for these applications.
