The self-sufficient measuring device for precise water content/moisture determination, pressure and temperature measurement in the running process. The modular system allows the respective adaptation to different requirements. It guarantees the highest quality and safety in EX-protected environments. In the production, further processing and refinement of very many emulsions and bulk materials.

The Litronic WMS can be used to meet the majority of measurement requirements for determining the water content in liquids. The associated PC software "WIO" enables fast and exact calibration of the measuring sections.

Modular system for monitoring pipelines, tanks and refineries


Litronic WMS II Rod Sensor P45-GD for measuring water content, pressure and temperature

The newly developed Liebherr measuring system Litronic WMS II for water content/moisture determination of various liquids and materials. Developed for use in refineries, on oil platforms and in pipelines, various applications in the chemical and petrochemical industry and in maritime industries, among others. Thus, the P45-GD rod sensor installed in marine fuel tanks can guarantee the highest quality and safety even in EX-protected environments when determining the water content during ongoing tank processes of marine fuels.


The modular rod sensor for installation in tanks and pipelines is available in various rod lengths and can be used up to 100 bar. Pressure sensor, sliding and interchangeable fittings are optional. In addition to pressure monitoring, temperature measurement in the process is also possible.


In addition to their high precision and robustness, Liebherr measuring devices are characterised by their reproducibility. Once the system has been calibrated, further measuring points can be set up or devices renewed on this basis at any time without great effort. The system thus always remains reliable, regardless of its previous running time and age.
