Water content determination Litronic-WMS II

Water cut meter / Analyzer

Liebherr sensors in use in explosive areas

The Liebherr Litronic-WMS II water content meter is used to measure the moisture or water content of a wide range of water content of a wide variety of media and materials in refineries, on oil platforms, in pipelines, in tanks, in many applications in the chemical and petrochemical industry, sludge dewatering, drying, waste incineration and sewage treatment plants. Also in the agricultural sector up to the pharmaceutical industry and many other industries.

The wide range of applications extends from the most diverse emulsions to the finest powders and dusts and coarse-grained materials (max. grain size 32 mm) such as

- Oil, crude oil, diesel, biodiesel, hardening oil (upstream / downstream)

- Coolants

- Paints, lacquers, solvents

- Wax, resin

- Other emulsions, suspensions

- Water-product separation

- Dust, slag

- Fertiliser

- Washing powder, agent

- Sawdust

- Biomass

- Flour

- etc.

Applications:

- Water cut meter

- Pipeline, tanks BS&W (Basic sediment and water) measurement

- Petroleum purification/desalination

- Automatic well testing

- LACT units

- Separation control

The stand-alone and precise measuring device for water content/moisture determination in the running process guarantees the highest quality and safety in EX-protected production environments, the further processing and refinement of very many emulsions and bulk materials.

The software enables fast and accurate calibration of the measured sections.

In addition to their high precision and robustness, the measuring devices from Bad Schussenried 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 plant thus always remains reliable, regardless of its previous term and age.
