Introduction
Efficient dredging relies on the optimal balance between the density and flow rate of dredged materials. Accurate monitoring of production is essential for maximizing yields and minimizing environmental impact. Radiometric density measurement is a proven method in the dredging industry, offering benefits such as reduced over-dredging and operational costs.

Density Measurement System
Berthold's density measurement system is mounted on the pipeline's outer wall, providing stable readings under harsh conditions. It works in conjunction with a flow rate signal to deliver reliable production data. The system is non-contacting, ensuring no wear or maintenance is required.

Advantages

• Outstanding sensitivity and accuracy
• Real-time measurement during operation
• High stability through patented sensitivity control
• Contactless measurement prevents wear
• Easy installation without pipeline modification

Features

• SuperSENS detector for low source activities
• Compact and detached detector systems available

LB 474 Density Measurement System
The LB 474 system is used for online density monitoring. It can measure both density and mass flow when combined with a flow rate meter. The system is unaffected by extreme conditions and requires no maintenance. Safety is ensured with a sealed gamma radiation source and optional pneumatic shutter mechanism.

Efficient Dredging
Combining density measurement with a flow rate meter provides current production data, displayed via a cross-needle indicator. The cross-point indicates the net dredging result.
