Apparatus and method for measuring drop volume

摘要

A computer-based apparatus, including: a memory element storing computer readable instructions; a processor; and a source element to expel a first plurality of drops of a substance with a known density through a medium, and under a set of conditions. The processor executes the computer readable instructions to calculate uncalibrated volumes for the first plurality of drops using respective images of drops in the first plurality of drops. The source element expels a second plurality of drops of the first substance through the medium, and under the first conditions. The processor executes the computer readable instructions to: calculate, using a weight for the second plurality of drops and the known density, actual volumes for the second plurality of drops; and generate, using uncalibrated volumes and the actual volumes, an equation to modify the uncalibrated volumes to match the actual volumes.

1. A computer-based method for measuring volume of a drop, comprising:
storing, in a memory element of a computer, computer readable instructions; expelling a first plurality of drops of a first substance from a source element, through a medium, and under at least one condition, wherein a density of the first substance is known; executing, using a processor for the computer, the computer readable instructions to: generate respective images of drops in the first plurality of drops as the drops are passing through the medium; calculate an uncalibrated volume for the first plurality of drops using the respective images of the drops in the first plurality of drops; expelling a second plurality of drops of the first substance from the source element, through the medium, and under the at least one condition; and, executing, using the processor, the computer readable instructions to:
calculate, using a weight for the second plurality of drops and the known density, an actual volume for the second plurality of drops; and,generate, using the uncalibrated volume and the actual volume, an equation to modify the uncalibrated volume to match the actual volume, wherein: expelling the first plurality of drops under at least one condition includes exposing the first plurality of drops to a first physical condition affecting the medium:
after the first plurality of drops has been expelled from the source element;while the first plurality of drops is passing through the medium; and,before travel of the first plurality of drops through the medium has terminated; expelling the second plurality of drops under the at least one condition includes exposing the first plurality of drops to the first physical condition affecting the medium:
after the second plurality of drops has been expelled from the source element;while the second plurality of drops is passing through the medium; and,before travel of the second plurality of drops through the medium has terminated.
