Drainability measurement

摘要

A measurement device measures a liquid flow discharged from a funnel in a lower branch and/or a side branch. A modelling function is established between liquid flows received with the funnel and/or liquid flows discharged through the lower branch and/or the side branch. In drainability measurement, a sensor measures the flow through a wire out of a measurement chamber at least at two points in time. A processor establishes a parameter descriptive of the drainability from flows measured at the different points in time based on a modelling function stored in a memory.

1. A method of modelling the drainability measurement of a suspension, the method comprising:
receiving known liquid flows of water or known suspension with a funnel, each of which fills the funnel in such a manner that the liquid flows from a side branch; measuring, for each known liquid flow received with the funnel, each flow of a lower branch and/or each flow of the side branch; and establishing a modelling function based on the measurements between the flows of the lower branch and/or the flows of the side branch and the known liquid flows received with the funnel.
