Concentration and water content measurement LB 566

Microwave based analyzer for measuring dry substance, water content and density

MicroPolar is the latest microwave based online analyzer for the reliable measurement of 

  • Dry substance
  • Water content
  • Density (e.g. in g/l or °Bé)

Concentration and water content measurement MicroPolar can be used for various fluids, pastes and powders. The system is favored also for the concentration measurement of suspensions, as the sensor's robust design ensures high abrasion resistance and a reliable operation for many years. The fields of application are manifold, ranging from the food industry to the wastewater, power generating and chemical industry.
We provide sensor systems for the installation either on pipelines or on vessels and tanks. The high-dynamic version of our microwave transmitter MicroPolar++ provides an excellent measuring accuracy, even for large pipeline diameters.

Our concentration and water content measurement - your advantages at a glance

  •     Cost-optimized production do to real-time measurement
  •     Representative, exact and reliable
  •     Non-contact and low-maintenance
  •     Simple on-site calibration

New container probes for concentration and water content measurement measurement

The new, removable plastic caps made of PEEK with internal thread can be exchanged on site if necessary. The newly developed antenna technology inside ensures higher measurement accuracy and offers more dynamics.

New FlowCell with EHEDG certification

The new FlowCell consists of a stainless steel inline housing and two microwave antennas which are connected via clamp connections and are interchangeable at any time. Due to the certification of the EHEDG it is also suitable for hygienic applications.

Our applications/solutions for concentration and water content measurement


Measuring density of milk of lime in the purification process




Multi-frequency Technology

The measurement is performed with a number of different frequencies per measurement cycle, leading to a very stable and reliable measurement, unaffected by reflexes or resonances.

High Dynamics

The high dynamic range of MicroPolar allows the precise determination of concentration on very large pipeline diameters.

Reference Line

An integrated reference line makes the measurement independent from potential environmental influences.

Automatic on-site calibration

The calibration is carried out directly on the transmitter. The software contains a sample taking feature, where laboratory values can be easily entered. The calibration curve is calculated automatically.
