Level measurement using radar technology


in which accurate and reliable level measurements are essential. These measurements play a crucial role in reducing chemical use, product variability and energy costs; optimising production and storage efficiency; and increasing plant and worker safety.


T


he various stages of the pulp production process involve a broad range of applications


The severe operating conditions commonly encountered in pulp mills can prove difficult for level measurement instrumentation. Ingemar Serneby* explains how the latest non-contact radar transmitters meet these challenges


However, the severe operating


conditions in pulp mills present challenges for most level measurement technologies. These include turbulence, foaming surfaces, corrosive


chemicals, condensation, viscous materials, density and pressure variability, high temperatures, dust generation, and media with a low dielectric constant. It is therefore essential to select


Conditions in pulp mills can be challenging for measurement systems


instrumentation that can best overcome these challenges to provide the high degree of level measurement certainty they require.


Measurement technologies Various technologies can be employed to monitor and
