A calibration system for a dimensioner is described. The calibration system uses a reference pattern with multiple optically-perceptible elements. The optically-perceptible elements have a parameter associated with size and are separated from each other by predefined distance. The dimensioner captures an image of an object and calculates physical dimensions of the object. The dimensioner captures an image of the reference pattern. The dimensioner measures the parameter associated with size for a pair of optically-perceptible elements and measures the distance between the pair of optically-perceptible elements from the captured image. The dimensioner then calculates a ratio between measured parameter for the pair of the optically-perceptible elements and of a predefined distance between the pair of the optically-perceptible elements. The calculated ratio is compared with a actual reference ratio to determine if calibration is needed. The dimensioner is calibrated based on the calculated ratio.

In various embodiments, a known fluid volume comprising a sample line fluid and a secondary fluid is delivered to a fluid boundary sensor. The fluid boundary sensor assists in determining the position of the boundaries between the various fluids, and the positions of these boundaries are used to determine the sample line fluid volume.

Methods and devices for measuring the volume of a liquid sample transferred from a source to a destination by means of incremental dispensing of the sample into a destination vessel or by means of decremental aspiration of the sample from a source vessel, where the liquid sample is collected from a liquid having known optical absorbance at a known wavelength or within a defined part of the electromagnetic spectrum. The absorbance of the sample is measured by exposing the source or destination vessel to electromagnetic radiation before and after the transfer, and the liquid volume is determined on the basis of differential measurements of absorbance of the source or destination vessel.

Various corporate, industry, and regulatory guidelines, best practices and standards are used in establishing acceptable levels of accuracy for volume dimensioning systems used in commerce. A volume dimensioning system can determine at least one distortion value that is indicative of an amount of distortion present in the system and responsive to the amount of distortion, autonomously alter or adjust the units of accuracy of information reported by the system. Such alteration or adjustment of units of accuracy may be performed based on an assessment of the distortion relative to a number of distortion thresholds. Responsive to the assessment, the volume dimensioning system can adjust a unit of accuracy in a representation of volume dimensioning related information.
