An addition system for introducing particulate material into an industrial process is disclosed. The addition system comprises a vessel for holding the particulate material, wherein the vessel has a top and a bottom; one or more weighing devices; a controller for controlling operation of the addition system; a base plate to support the vessel and optionally the controller; and three or more legs, each leg having an uppermost section that connects to the vessel and a foot that is connected to the base plate. The widest diameter of the vessel is less than the diameter of a circle drawn through the feet of the legs. The one or more weighing device are mounted on the base plate and support the legs of the vessel.

A method is provided for measuring an energy efficiency of a quantitative weighing device. A data measurement part is formed by: recording a control time of fast charging, recording a control time of slow charging, recording a comparison prohibition time, and recording weighing data. A current device reliability parameter, a fast charging feed flow, and a slow charging feed flow are calculated, based on the comparison prohibition time and the control time of slow charging. The fastest feed time under a requirement of a target reliability parameter is calculated as the difference between the target reliability parameter and the calculated control reliability parameter. By using the method, application data, such as capability of a quantitative control device and energy efficiency of the quantitative weighing device, can be intuitively obtained. This facilitates commissioning, maintenance, and use of the quantitative weighing control device.

The present invention relates to a sample diluting and dispensing device. The sample diluting and dispensing device according to the present invention includes: a sample holding plate in which a holding part for holding a plurality of sample vessels is formed; a moving unit for transferring the sample holding plate in a plane direction and a height direction; a sample supply unit for supplying a sample to the sample vessel; a diluent supply unit for supplying a diluent to the sample vessel; a scale installed below the sample holding plate to measure a weight of the sample vessel; and a controller for receiving a weight measurement result from the scale and controlling an operation of each of the sample holding plate, the sample supply unit, and the diluent supply unit.

An automated granule portioning system includes at least one volumetric measuring chamber capable of adjusting the volume of the chamber automatically to a programmed target volume and arranged to receive a first portion of granules into the chamber to fill the target volume. A transport system automatically delivers the target volume of granules from the chamber to a weighing device. A granule metering device dispenses granules and, depending on a signal from the weighing device that the first portion of granules is below a programmed target weight, dispenses granules to the first portion to increase the weight to achieve a second portion having the target weight.
