RHEOTUNE® Fluid Mud Rheometry Probe The RheoTune is the state of the art successor of the DensiTune Silt Density probe, with its proven track record in nautical depth assessment worldwide. Ongoing research on the tuning fork respons in fluid and semi fluid muds 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 handson measuring device. The RheoTune provides fast and accurately vertical rheometric profiles (yieldstrength and viscosity) and possesses complete DensiTune functionality. The RheoTune is delivered with a factory calibration for both yield strength and density. The RheoTune will be your partner in: • Waterbottom stability assessment in coastal studies • Managing dredging resources and disposal area’s • Monitoring of siltation quantities • Assurance of the nautical accessibility of your harbour 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 optimised to integrate with the SILAS seismic profiling system. The SILAS real-time density mapper allows rapid tracing of critical locations that require in-situ probing. RheoTune: • • • • Simultaneous yield, density and viscosity Calibration free yield strength Supports fully automated winch operation Highspeed ethernet datatransmission • Fast update rate
