Because of the increased regulation around the use of nuclear based density monitors, many companies are exploring new ways of measuring density. A non-nuclear approach reduces safety related costs and is a more sustainable solution to the issue of density measurement in slurries.
In this case study, a hydroelectric power generation company tested three different density measurement technologies including the Rhosonics SDM to assess suitability for their process water. For maintenance, sediments are dredged from the uphill basin and transported to the river downhill. A certain water/solids balance is needed to prevent accumulation of sediment in the flow from the power plant to the river. Additionally, the company has to be conscious of the effect of wear caused by solids on the turbine of the plant.
