RheoTune® is an advanced rheometric profiling system developed for accurate nautical depth determination in fluid mud environments. As the successor to the proven DensiTune system, RheoTune combines density, yield strength, and viscosity measurements in one versatile solution, providing detailed insight into the characteristics of fluid and semi-fluid mud layers.

The system is pre-calibrated, allowing for fast deployment and efficient data acquisition in the field. Using proprietary acquisition and processing software, RheoTune delivers near real-time visualization of vertical rheometric profiles, helping operators quickly assess water bottom conditions and sediment behaviour.

RheoTune is widely used for harbour accessibility assessments, dredging management, coastal studies, and sediment monitoring. By measuring both rheological and density properties, the system provides highly reliable input for determining nautical depth and improving operational decision-making.

Designed for flexibility, RheoTune can be operated from small survey vessels or fixed installations and can be combined with automated or manual winch systems for increased productivity. The solution also integrates seamlessly with SILAS acoustic profiling software, enabling a complete overview of fluid mud layers and critical sediment locations.

With its proven accuracy, stability, and worldwide track record, RheoTune has become a trusted solution for ports, dredging contractors, and hydrographic professionals looking for efficient and reliable nautical depth surveys.
