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.
Claims18
A method for determining, in situ, a weight of material entrained in a fluid flowing in a duct segment, said method comprising the steps of:
- weighing said duct segment having material free fluid flowing therein to obtain a first weight, wherein said duct segment is in fluid communication with a conveying system;
- weighing said duct segment having a mixture of material and fluid flowing therein to obtain a second weight;
- subtracting said first weight from said second weight to determine, in situ, said weight of said material in said duct segment.
A device for determining, in situ, a weight of a material entrained in a fluid flowing in a duct in a conveying system, said device comprising:
- a duct segment in fluid communication with said conveying system;
- and
- isolation fittings for coupling said duct segment to adjacent portions of said conveying system, wherein a weight of said duct segment is measured independent of a weight of said adjacent portions of said conveying system.
A device in accordance with 9, wherein said support mechanism comprising at least one of a scale and a load cell.
