The present invention relates generally to weight measurement methods and systems, and more specifically, to weight measurement methods and systems for material in a dynamic vacuum material transfer or other system utilizing differential conveying fluid pressure. The invention determines a corrected weight of a batching tank. The invention includes measuring and logging weights and pressures while the batching tank is being evacuated and determining the density of the air in the batching tank at one or more pressures. While material is being transferred into the vessel the invention measures the weight and pressure of the batching tank and calculates the corrected weight based on logged weights, logged pressures, and the density of the material added to the batching tank.

What is claimed is: 1. A material transfer system for transferring a material to a batching tank, the batching tank having a weight, a pressure, and a volume, the batching tank initially comprising a fluid, the fluid having a density, the material having a density, the system comprising: a vacuum pump, the vacuum pump removeably connected to the batching tank and operable to remove fluid from the batching tank; a weight measurement device operable to measure one or more first weights of the batching tank and a second weight of the batching tank, the weight measurement device having an output; a pressure measurement device operable to measure one or more first pressures in the batching tank and a second pressure in the batching tank, the pressure measurement device having an output; one or more valves for allowing the material to enter the batching tank, each valve having a control input; and a control unit in communication with the output of the weight measurement device and the output of the pressure measurement device, the control unit operable to record one or more first weights measured by the weight measurement device and one or more first pressures measured by the pressure measurement device, and the control unit operable to determine a corrected weight; wherein the control unit is operable to: receive one or more first weights from the weight measurement device; receive one or more first pressures from the pressure measurement device; operating one of the valves, causing material to be transferred to the batching tank; receive a second weight from the weight measurement device, wherein the second weight is determined while material is being transferred into the batching tank; receive a second pressure from the pressure measurement device, wherein the second pressure is measured substantially simultaneously with measurement of the second weight; and determine a corrected weight based on the second weight, the second pressure, one or more first weights, one or more first pressures, and one or more material properties. 2. The material transfer system according to claim 1 wherein the control unit is operable to: determine a volume occupied by the fluid; determine a volume occupied by the material; determine a fluid weight by multiplying the volume occupied by the fluid by the density of the fluid; determine a material weight by multiplying the volume occupied by the material by the density of the material; and determine the corrected weight by adding the material weight and the fluid weight. 3. The material transfer system according to claim 1 wherein the control unit is operable to: select a first weight, wherein the first weight was measured substantially simultaneously with the closest first pressure, and wherein the closest first pressure is nearest the second pressure; and calculate the density of the fluid by dividing the selected first weight by the volume of the batching tank. 4. The material transfer system according to claim 1 wherein the control unit is operable to close one of the valves to halt material from flowing into the batching tank. 5. The material transfer system according to claim 1 wherein the control unit is operable to: log the one or more first weights, wherein each first weights are measured while the fluid is removed from the batching tank; and log the one or more first pressures, wherein each first pressure is measured substantially simultaneously with the measurement of the first weight. 6. The material transfer system according to claim 4 wherein the control unit is operable to close one of the valves to halt the flow of material when the corrected weight is near a target weight.
