State of the art measurement technology

Bulk flow measuring principle by Berthold!

The noncontact radiometric bulk flow measurement works with a scintillation detector installed above and a shielded source mounted below the conveying system. Radiation is directed through the conveyor and attenuated as it passes through the conveyor and product. The extent to which it is attenuated depends on the conveyor load.
In addition to the standard high accuracy arrangement with rod source and point detector, we also offer fan beam sources and rod detectors for an economical but reliable measurement.

The specialist for bulk flow measurements

Besides current flow rate the systems also provide total solids mass (tonnage) and batch measurements. Applications of Berthold belt scales are found in all different bulk handling industries from mining to the building materials industry, from chemical plants and power plants to the pulp & paper industry. Customers benefit from improved control in mixing processes, compliance to delivery contracts and optimal utilization of loading capacities. Worldwide there are more than 2000 systems successfully in operation.

Technological Highlights

Quality and safety

  • Non-contacting
  • High accuracy and reliability
  • Maintenance-free operation
  • Highly robust, suitable for the most demanding and hostile of process conditions

Simple and intuitive operation

  • Wear-free system components
  • Easy to install on existing conveyors without modification or process downtime 
  • Measurement is carried out on belt, screw, drag chain or vibrating conveyor, or possibly on a chute

Whitepaper “Rod source / point detector"

Berthold has published the whitepaper “Rod source / point detector arrangement”, wherein the advantages and benefits of a rod source/point detector arrangement are explained. Due to less frequent production downtimes, simpler and thus more economical spare parts inventory, increased long-term and temperature stability and consistent process quality, the higher acquisition costs are mitigated within a short period of time.
