- Non-optical measurement, therefore unaffected by impurities
Measuring total solids concentration at the secondary clarifier and return sludge
The MicroPolar microwave measuring system uses the dielectric property of water. The measuring system generates microwaves that interact with the dipolar water molecules and causes them to rotate This interaction causes an attenuation of the microwave energy, which can be detected as phase shift and attenuation. Since the phase shift and attenuation change is directly proportional to the water content, the concentration of the medium can be determined with high accuracy.
Berthold‘s superior multi-frequency technology provides very stable and reliable measurements that are unaffected by interfering reflections or resonances. The microwave power of a MicroPolar measurement system is so low (max. 10 mW) that the material being measured is neither heated nor altered in any way.
