Flow-rate measurement assembly according to the differential-pressure measurement principle

The invention relates to a flow-rate measurement assembly for measuring a flow rate of a medium (2) through a measurement pipe (3), comprising at least one differential-pressure producer (4), which is located in the measurement pipe (3) and which effects a drop in the media pressure, which drop depe...

Summary:The invention relates to a flow-rate measurement assembly for measuring a flow rate of a medium (2) through a measurement pipe (3), comprising at least one differential-pressure producer (4), which is located in the measurement pipe (3) and which effects a drop in the media pressure, which drop depends on the flow rate, and comprising a differential-pressure measurement transducer (5) for providing a differential-pressure measurement signal (22), which depends on the difference between the high-pressure-side media pressure and the low-pressure-side media pressure, wherein the difference is a measure of the flow rate of the medium (2), wherein the evaluating unit (10) is designed to determine a relationship between the differential-pressure measurement signal (22) and a characteristic parameter of a fluctuation of the differential-pressure measurement signal (22), to judge the determination of a monotonically decreasing relationship between the differential-pressure measurement signal (22) and the characterist
