Sciamworldwide Presentation

1. Sciam Worldwide designs, patents and
manufactures the DM3 Density Meter,
a Non-Nuclear density sensor and mass
flow system. The DM3 measures, transmits
and displays wet density or sg and % dry
solids of slurries.

15. Savings Example - Dredging
A comprehensive survey was done on dredgers operating on the Hudson River in USA
(Reference: Baier, J.L., Douglas, W.S., Gimello, R.J., Lodge, J.). The various costs of dredging are
comprehensively provided in this reference, a typical example is provided below.
Breakdown of Costs
Average cost of dredging $50 / yard³ per dredger
Average dredged volume per day 8500 yard³ per dredger
Average dredged volume per 360 day year 3.06 million yard³ per dredger
Cost per year $150 million per year per dredger
Nuclear density meter typical overall accuracy 2%
Cost of Ambiguity $3.0 million per year
Sciam Density Meter typical overall accuracy 0.285%
Cost of Ambiguity $427,500
Savings realized with Sciam DM3 $2,572,500 Per Dredger
Per Year
