RheoTune



The RheoTune is the state of the art successor of the DensiTune Silt Density probe, with its proven track record in nautical depth survey worldwide. Ongoing research on the tuning fork response in fluid and semi fluid mud has led to an in-situ measurement system to assess rheological characteristics. These parameters are the direct relevant input for nautical depth assessment and coastal studies. Stema Survey, the specialist in tuning fork silt measurement systems, succeeded to implement the theoretical background into a hands-on measuring device. The RheoTune provides fast and accurately vertical rheometric profiles (yield strength and viscosity). Furthermore it possess all functionality of the DensiTune.
 

The RheoTune will be your partner in:

• Assurance of the nautical accessibility of your harbour.
• Water bottom stability assessment in coastal studies.
• Managing dredging resources and disposal area's.
• Monitoring of siltation quantities.

The RheoTune is a versatile system to be operated from the smallest vessel or stationary installation. To increase productivity an intelligent winch system is available for fully automated operation. The RheoTune is optimized to integrate with the SILAS acoustic profiling system. The SILAS on-line density mapper allows rapid tracing of critical locations that require in-situ probing.
