A method and test apparatus determines a volume of a droplet of liquid. The test apparatus deposits a drop of liquid to be measured on a surface that provides a known contact angle with the liquid under the deposition conditions used, thereby establishing one of: (i) an advancing, (ii) a receding, and (iii) an intermediate contact angle. The test apparatus images the drop. The test apparatus measures a dimension of height or diameter of the drop. In one embodiment, the test apparatus calculates a volume of the drop of liquid from the relationship of the contact angle to one or more parameters selected from the maximum height, the diameter of the contact patch, the radius of curvature, or the cross sectional area of the drop.

Providing a sample-measurement container having a known volume. Inserting the crude-oil sample into the sample-measurement container, the crude-oil sample occupying the known-volume of the sample-measurement container. Exposing the crude-oil sample in the sample-measurement container to a halogen lighting-unit. Separating the basic-sediment and the water from the oil in the crude-oil in the sample-measurement container. Calculating the fraction-of-oil by volume in the crude-oil sample after the basic-sediment and the water has separated. The method for separating basic-sediment and water (BS&W) from oil in an oil field crude-oil sample using a halogen lighting unit and a sample-measurement container is useful for field tests of crude-oil samples.

A system for monitoring the volume of fluid in a hydration pack comprises a monitoring unit which is attached to an output of the hydration pack and to a feed tube. The monitoring unit comprises a pressure sensor and a tilt sensor. The pressure sensor obtains a measure of pressure of fluid within the hydration pack that may be used to estimate remaining fluid in the hydration pack. The tilt sensor is able to provide adjustment parameters tor adjusting for changes in pressure due to tilt of the hydration pack. An application on a mobile telephone provides a user with an indication of remaining liquid in the hydration pack. The application provides a visual indication of remaining fluid and may also provide an indication of rate of consumption. The application may also calibrate the system, enabling the system to be fitted to existing hydration pack assemblies.

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.
