Measuring density for dredging

Mounted around the outside of the pipe, Berthold‘s density measurement system provides superior and stable readings despite harsh environmental conditions. In combination with a flow rate signal, the radiometric density measurement delivers highly reliable live information about production.
Berthold‘s density measurement solution for dredging applications are used for continuous process control on pipelines. During measurement, the flow properties of your system are not affected due to the non-contacting method. This results in a wear and maintenance-free system.
To obtain information about the current production, the density measurement must be combined with a separate flow rate meter.

Density measurement with LB 474

Berthold‘s density measurement system LB 474 is used for online density  monitoring. With a second LB 474 and a flow rate meter, it is possible to measure both the density and mass flow (total mass flow or mass flow of the solids). Extreme measuring conditions like vibration, weather, or varying particle size and composition do not effect the measuring performance. Due to the sophisticated stabilization of the detector performance, the highly accurate measuring results are guaranteed for many years of operation and no maintenance is required at any time.
Since the gamma radiation source (Co-60 or Cs-137) is sealed safely inside a compact shield, the highest operational safety is given.
