Abstract
A device for determining density of a material flowing in a conveying system includes a duct segment in fluid communication with the conveying system. The duct segment is coupled to the conveying system by isolation fittings, which allow the weight of the duct segment to be measured independent of the weight of adjacent portions of the conveying system. Further, a method for determining density of a material flowing in a conveying system includes weighing a duct segment having material free fluid flowing therein. The duct segment having a mixture of material and fluid flowing therein is also weighed. The difference of the two weights is used to determine a linear density of the material.
