Abstract

Keksintö koskee menetelmää paperikoneen perälaatikon virtauspinnan tasomaisuuden mittauksessa. Tasomaisuus määritetään asettamalla mittatyökalu (21) virtauspinnan muodostamalle tasopinnalle (20) ja mittaamalla kussakin kohdassa mittatyökalun (21) asema. Mittatyökaluun (21) järjestetään mittausanturi (24) mittatyökalun (21) ja tasonpinnan (20) välisen etäisyyden mittaamiseksi. Lisäksi luetaan mittausanturien (24) antamat mitat ja yhdistetään mittatyökalun (21) asema ja mitat mittausantureilta (24) mitattujen kohtien arvojen määrittämiseksi. Keksintö koskee lisäksi laitteistoa paperikoneen perälaatikon virtauspinnan tasomaisuuden mittauksessa. Kuva.2
