Abstract

Föreliggande uppfinning avser en anordning för monitorering av sedimentering i system som innehåller processvätskor, till exempel processvatten. Uppfinningen avser även användning av nämnda anordning och nämnda förfarande för monitorering av utfällning på ytor. Föreliggande uppfinning avser även inmatning av fällningsinhibitorer. Anordningen innefattar en överflödestank (2) av vätska (L) för uppsamling från vätskeprocessen, en avtappningsenhet (3) för avtappning vätska (L) från nämnda överflödestank (2), en till nämnda avtappningsenhet (3) ansluten strömningsmätningsenhet (4) för mätning av strömningshastigheten för monitorering av den utfällning som sker på ytor.The present invention relates to a device for monitoring sedimentation in systems containing process liquids, for example process water. The invention also relates to the use of said device and said method for monitoring precipitation on surfaces. The present invention also relates to the feeding of precipitation inhibitors. The device comprises an overflow tank (2) of liquid (L) for collection from the liquid process, a tapping unit (3) for tapping liquid (L) from said overflow tank (2), a flow measurement unit (4) connected to said tapping unit (3) for measuring the flow rate for monitoring the precipitation that occurs on surfaces.
