Solution Overview
Problem
Existing methods for determining the quantity of liquids, such as milk, during transfer are limited by the degassing arrangement, which restricts transfer performance and requires large volumes, especially when gas inclusions occur, leading to inefficiencies and increased transfer times.
Innovation Solution
The method involves continuously monitoring the need for degassing using a gas bubble detection device and dividing the liquid flow to bypass the degassing arrangement when not necessary, allowing the liquid to be guided past it and merged downstream, thereby maximizing transfer performance and maintaining continuous flow without interruption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the liquid is continuously passed through the degassing arrangement to ensure complete degassing, then measurement accuracy is improved, but transfer performance is reduced and transfer time increases
Solution Approach 1:
The liquid flow is divided into two separate streams: one passing through the degassing arrangement for complete degassing and measurement, and another bypassing the degassing arrangement for rapid transfer. This segmentation allows the system to simultaneously achieve accurate measurement and high transfer performance by processing different portions of the liquid through different paths.
Solution Approach 2:
Instead of requiring all liquid to undergo complete degassing, the system applies partial degassing action only to the portion of liquid that needs precise measurement, while the remaining liquid bypasses this step. This partial action approach maintains measurement accuracy for the measured portion while avoiding the time penalty for the entire flow.
2Productivity
If the degassing arrangement volume is increased to handle higher transfer performance, then productivity is improved, but device complexity and space requirements increase
Solution Approach 1:
The system segments the liquid flow so that only a portion passes through the degassing arrangement at any given time. This allows the use of a smaller, more compact degassing arrangement volume while still maintaining the required transfer performance, as the bypass stream handles the volume capacity requirement.
Solution Approach 2:
The measuring line serves multiple functions: it acts as both a transfer conduit and a measurement path. By integrating the measurement function into the bypass line, the system eliminates the need for a separate large-volume measurement chamber, reducing overall device complexity while maintaining productivity.

Implementation Method 2
the gas inclusions in the liquid to be transferred separate over the free surface of a respective subset of this liquid, which must remain in the degassing arrangement for a sufficiently long time and there due to the gas bubble buoyancy and/or by the Centrifugal force of a tangential velocity component of a rotational flow degasses
Implementation Method 3
the gas inclusions in the liquid to be transferred separate over the free surface of a respective subset of this liquid, which must remain in the degassing arrangement for a sufficiently long time and there due to the gas bubble buoyancy and/or by the Centrifugal force of a tangential velocity component of a rotational flow degasses

AI summary
The invention relates to a method for determining a quantity when transferring a liquid, particularly milk, and specifically during the process of transferring said milk from a supply vessel of a supplier to a collection tank of a transport vehicle, of a dairy, for example, according to the preamble of claim 1, and to a device for carrying out the method according to the preamble of claim 24. It is the aim of the present invention to ensure in a method and a device of the type in question that, when a large amount is transferred through the measuring line, the degasification unit loses its function of limiting the transferred amount, and a reliable and accurate quantity determination of the transferred liquid is ensured. This aim is achieved by the method in that ° the degasification unit (2) is continuously acted on for the entire duration of the transfer; ° the necessity to degas the liquid to be transferred is continuously ascertained upstream of the degasification unit (2) by way of a gas bubble detection element (3); ° prior to reaching the degasification unit (2), and optionally if no need for degasification exists, the liquid to be transferred is divided and branched off; and ° the part of the liquid to be transferred that is not fed to the degasification unit (2) is conducted past the degasification unit (2), and downstream of the degasification unit (2), it is merged with the liquid emerging from said unit and the merged liquid is fed to the throughput measuring device (4).
