Technological Highlights

Simple and intuitive operation

  • Noncontact, continuous measurement
  • Complete stainless steel construction of measuring section
  • Easy installation in existing pipelines


State of the art technology

  • Minimum radiation exposure
  • High statistical accuracy and longterm stability
  • Very simple calibration
  • Mass flow evaluation

Features for high demands

Due to its low radiation energy, an Am-241 source is used whose energy is comparable to that of x-rays and whose half-life time is about several hundred years. The LB 379 provides a high statistical accuracy and long-term stability by the use of highly senstitive scintillation detectors with the patented drift compensation.
The system is flanged to the pipeline. It is completely made from stainless steel and is also available with Teflon lining for a wear resistant operation for products with high viscosity and high solids content.

LB 379 Measuring unit for special applications

Due to the use of the low-energy isotope Am-241 or Cm-244, the LB 379 is able to detect elements depending on their atomic number.
This way, the concentration can be determined even if the density of the mixture changes only slightly or not at all.
Application examples: %HCI, %H2SO4 and %Zn in aqueous solution.
