    Abstract: A method for precisely and accurately determining the volume of a test liquid aliquot which can be used to calibrate a liquid delivery device. The method is particularly useful for determining the volume of an aliquot of a test liquid which is complex or non-aqueous, or is both complex and non-aqueous. The test-stock mixture contains at least the test liquid and a stock solution including a first dye, the first dye having absorbance characteristics which are measurably distinguishable from the absorbance characteristics of a second dye. The test-stock mixture is mixed with a diluent including the second dye to form a sample solution to be used to measure absorbances of the first dye and the second dye. The volume of the test-stock mixture aliquot is calculated by using a formula based on the Beer-Lambert law which incorporates the measured absorbance values and a dilution characteristic of the test-stock mixture. The test liquid and the stock solution are combined gravimetrically in a controlled ratio so that the flow characteristics of the test-stock mixture correspond to the flow characteristics of the test liquid and without affecting the ability to distinguish the absorbance characteristics between the first dye and the second dye.

    Abstract: The invention relates to a device (1) for dispensing or aspirating/dispensing liquid samples, comprising a pump (2) and a micro-ejection device (3), said micro-ejection device (3) having a pulse generator (4) with a chamber (5). Said pulse generator (4) is used to produce pressure waves in the liquid in order to cause the samples of a liquid to be dispensed. The micro-ejection device (3) also comprises an end piece (6) and a liquid line (7) which connects the pulse generator (4) to the end piece (6). The pulse generator comprises a micro-actuator (10) which is configured to function in the same direction as that in which the pressure wave leaves the chamber (5). The inventive devices are characterised in that the chamber (5), in the area of the end facing away from the end piece (6), or the corresponding connecting element (14) has a narrowed section (16) which restricts any expansion of the pressure waves in the direction of the pump (2). The invention also relates to systems with multiple devices of this type.

    Abstract: In present invention, the correctness of the quantity of fuel flowing into the engine through fuel pump is determined by a 'load cell' in which the weight of the fuel is sensed by an electronic sensor, processed by a specially designed processing unit called analyzer and displayed as output on a screen using Bluetooth with option for taking printout also. The system is easy to use, cost- effective and accurate. A major advantage offered by the system over prior art systems is that it does not use flow sensors or graduated glass tubes. It is very compact thus portability is easy. It can be easily plugged into existing diesel fuel pump test benches or can be supplied as additional accessory for use in existing machines or as an integrated module with new machines.
