Abstract:
1. A self-monitoring flow measuring arrangement, comprising: a pipeline system flowed through by a medium; a control device installed in said pipeline system on the inlet side, which varies a flow rate of the total medium flowing into said pipeline system according to a predetermined, time-dependent periodic change profile, at least one flow measuring device installed in said pipeline system, which is located at a measuring location, which is located downstream said control device in the flow direction, and through which the medium flowing through said pipeline system flows, and which measures the flow rate of the medium at the measuring location; and a monitoring unit, which, based on said predetermined, time-dependent periodic change profile and the flow rates measured at said measuring location, monitors whether said measured flow rates follow said predetermined, time-dependent periodic change profile, and outputs an error report, when at least one of said measured flow rates deviates from said predetermined, time-dependent periodic change profile.
