Moisture and mass flow measurement on conveyor belts

Accurate information on mass flow and moisture content is essential for efficient material handling, reliable process control and consistent product quality. Berthold’s combined measurement solution determines both parameters continuously and in real time directly on the conveyor belt. Radiometric technology provides reliable mass flow measurement, while microwave technology with horn antennas determines the moisture content of the conveyed material. Both measurements are contactless and can be easily integrated into existing conveyor systems.

Typical applications for bulk flow and moisture

  • Recycling industry, e.g. plastic domestic waste
  • Agrar industry for example NPK fertiliser
  • Mining industry, e.g. concentrated apatite rock or sulfur extraction 
  • Food industry, e.g. bagasse processing after sugar extraction
  • Construction industry, e.g. gypsum (phosphoric co-product/residuum)

Measuring principle & function

Bulk flow measurement using radiometry

  • Reliable online monitoring on all conveyor systems, even where conventional methods cannot be used
  • Reliable adherence to delivery/production quantities
  • Optimal utilization of storage capacities
  • Optimal addition of raw materials in mixing processes hence, very fast amortization of the measurement
  • No recalibration or cleaning necessary

Microwave moisture measurement with horn antennas

  • Known moisture content when tendering / loading bulk material ensures consistently high quality of the products
  • Multifrequency technology for dynamic plausibility control of the raw signal
  • Easy installation, also on already existing conveyor systems
  • Wear-resistant and maintenance-free due to contactless measurement
  • Reliable long-term measurement without recalibration
