2.5 to 3.5% - a combination of Waste Activated (1% Solids +/-) and Primary clarifier sludge (8% solids +/-). Dilution through use of water. Currently a manual process creating large swings depending on operator attention.
O.k. But what do you want to measure? You wrote consistency. Do you mean viscosity? If so, why is it so much of importance? 2.5 to 3.5 % solids concentration. That is still close to water in terms of viscosity.
Sorry for asking questions and not giving answers. But that might still happen when I fully understand your post.
I need a way to qualitatively define the amount of solids going to the centrifuges. I have a flow rate so now I need some sort of consistency or density measurement. Visocsity isn't particularly useful since the sludge isn't consistent or linear or predictable with velocity.
