dotOcean, a supplier of marine and maritime measurement and sensor solutions, announced the availability of the DensX, a novel underwater sediment density profiler.
The DensX is an accurate in situ mud density measurement system, measuring densities between 1.0T/m³ and 1.5T/m³ with an accuracy of 0.25%. The DensX technology is based on X-ray and is a direct measurement method. The technology does not suffer from strong legislation restrictions like radioactive density measurement systems. The system weights 70kg and is able to intrude deep in soft sediment layers.
Along with the DensX comes a user friendly software that controls a fully automated winch. The software visualizes the density profile, the winch speed, the winch torque and the tilt of the DensX. When several density profiles are taken the software generates a mud grid and interpolated dredging volume.
Today the DensX is applied in ports and access channels to characterize mud layers, to measure density based nautical bottom criteria and to prepare and evaluate dredging works. The accurate density measurement capability allows to determine precisely the ton dry weight of dredging material.
The DensX completes dotOcean’s product portfolio of underwater sediment characterization profilers and is complementary to rheological instruments, such as the GraviProbe.
