Abstract

The invention relates to a degassing arrangement for degassing a flowing liquid in which a gas is dissolved with a flow channel (2) with a channel inlet (4) and a channel outlet (5), wherein the flow channel (2) comprises an initial zone (6), which has a narrowed flow cross-section compared to a flow cross-section preceding the initial zone (6), such that the velocity of the liquid flow (3) in the initial zone (6) is increased compared to a velocity of the liquid flow (3) before the initial zone (6) and thereby the static pressure of the liquid is reduced such that the gas is released from the liquid, wherein the flow channel (2) comprises a separation zone (8), which in the direction of flow (7) follows the initial zone (6) and in which released gas is separated from the liquid flow (3). It is proposed, that the separation zone (8) comprises an upper section (10) and a lower section (11), that the separation zone (8) has an enlarged flow cross-section compared to the smallest flow cross-section of the initial zone (6), such that the velocity of the liquid flow (3) is slower in the separation zone (8) than in the initial zone (6), that the gas bubbles in the separation zone (8) rise due to gravity along the separation zone (8), whereby degassed liquid collects in the lower section (11), that the degassed liquid flows out through the channel outlet (5), and, that a degassing outlet (9) is arranged at the upper section (10), through which the released gas flows out of the flow channel (2).

Abstract

A method for operating a weighing system comprises a balance and an electronic control apparatus, wherein a first weight value of a sample is compared with an initial minimum weight value of the weighing system and if the first weight value is smaller than the initial weight value, the weighing system is set in an adaptive weighing mode in which an adapted minimum weight value is determined based on the initial minimum weight value and a number of repeated weight measurements of the sample. The adapted minimum weight value is compared with an average weight value of the sample. Further, a weighing system, a computer program and a computer-readable storage medium are shown.

Abstract

A method for operating a balance includes: (a) introducing an ion cloud into a weighing chamber to bring an electrostatic charge state of a weighing sample towards an electrostatic neutral state, (b) detecting the neutral state, and (c) acquiring measured values of a weighing sensor, calculating therefrom a final weighing value representing the electrostatic neutral state, and outputting the final weighing value. When the ionizer is activated, the measured values of the weighing sensor are acquired, preliminary weighing values are calculated from the measured values and the final weighing value is calculated and output after a number of preliminary weighing values have been recognized as stable. During a recognition phase, positive and negative ion clouds are alternatingly generated, and during a neutralization phase, only ion clouds of that sign are generated that, in the recognition phase, had led to the larger changes within the preliminary weighing values.
