Abstract
The invention relates to a method and device for measuring and regulating the concentration, preferably of a fibre suspension, with the aid of a blade (1) pivotally suspended in the suspension. The blade (1) is caused to pivot such that its trailing end (8) moves between two end positions (A,B) in the suspension for providing a predetermined angular stroke (.alpha.). Time measurement is carried out when the trailing edge (8) of the blade (1) moves through its stroke from its upper end position (A) to its lower end position (B). The time obtained is a parabolic function of the concentration and varies in response to the shear force resistance in the fibre suspension of the blade (1) during its angular stroke, and thus in response to the concentration of solid substances in the suspension.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
