Concentration Measured for Dredging

Concentration Measurement for Dredging Applications

Efficient dredging is based on the optimum ratio between the solid concentration and flow rate of the dredged material. The radiometric measuring system LB 444 is used to monitor the concentration online. The non-contacting measurement is maintenance-free and as a result of the sophisticated detector stabilization, highly reliable measuring results are guaranteed for many years of operation. Vibration, weather or varying particle size and composition have no effect on the measuring performance. The use of high-sensitive scintillation detectors leads to superior measuring accuracy and to a significant reduction of source activity by up to 80% - depending on measuring conditions and system configuration.

In combination with a flow rate signal, the measurement provides reliable information about the yield and the total mass of dredged material.


• Highly accurate and repeatable

The high-sensitive scintillation detectors achieve a significantly increased accuracy compared to ion chambers or Geiger-Mueller tubes.

• Always at your service

With a worldwide network of engineers and service technicians, BERTHOLD TECHNOLOGIES is capable of supporting projects locally and around the world. Our qualified personnel will be at your site in no time at all.

• Lowest source sizes

Our detectors work with remarkably low source activities. Depending on the measuring conditions and system configuration, the activity can be reduced by 80%.

• Patented detector stabilization

Neither temperature nor aging of the electromechanical components affects the measuring performance. The highly reliable measurement is guaranteed during the entire operation.
