Nuclear vs. Ultrasonic

Posted on Wednesday, 12 January 2022 at 05:04

End-users in the mineral processing and dredging industries are often reporting issues related to their nuclear gauges. A few examples are: Regulations, disposal of the old source, radiation leakage inspections, storage, radiation safety training and transportation. For this reason, companies are seeking for alternative methods to measure the slurry density in their production processes.

There is a large need to migrate from nuclear density gauges to ultrasonic density meters. The transition to ultrasonic density meters will offer benefits such as reducing the operational costs and improving the safety on-site. The operational expenses are significantly reduced, because the ultrasonic density meters do not require repeated maintenance tasks and other expenses to comply with radiation safety regulations. Below you can find an example of the costs differences between nuclear and ultrasonic instruments. The purchase costs are comparable to the ultrasonic meter, but the installation costs in the nuclear sector in particular are higher because specialists have to be hired.

Nuclear density meters have been dominating the market for decades, but are nowadays no longer required in most of the typical slurry density measurement applications. Rhosonics is helping the industry to eliminate all costs and risks associated with the radiation source, by offering the ultrasonic Slurry Density Meter (SDM).

The Rhosonics Slurry Density Meter (SDM) has the following attractive features:

  • High accuracy and reproducibility
  • Compact and robust design
  • Easy installation and calibration
  • Maintenance free
  • In situ, no moving parts
  • High-end software technology that is easy to operate
  • Data logging capabilities
  • Supports various communication protocols, including Modbus, Profibus & HART (in combination with the Rhosonics RCU)
