The radiometric measuring system Uni-Probe LB 491 measures with density or concentration of liquids, slurries, or suspensions with no contact. The density meter has a current input for the volumetric flow and can therefore also be used for mass flow measurement on pipelines.

Simple and intuitive operation

  • Versatile detector for various applications
  • Solid system for standard applications
  • Can also be used for mass flow measurements

State of the art technology

  • Compact field device with integrated transmitter
  • Communication via HART, Foundation Fieldbus or Profibus PA
  • Communication can be switched from Bus to HART at any time

Robust detector for high demands
The Uni-Probe LB 491 is a compact field device, combining both detector and transmitter into one instrument. It provides interfaces for

  • HART
  • Profibus PA
  • Foundation Fieldbus

Even if the Uni-Probe LB 491 is used in Profibus or Fieldbus systems, it is always possible to switch to HART communication if required. In addition the separate 4-20mA current output can always be used as alternative signal output.

Key Facts

  • Compact density measurement using radiometric principles
