Description
Patentkrav 1. Fremgangsmåde til at kontrollere virkningen af korrosionsforebyggelse i et efterfølgende rørsystem kendetegnet ved at der i rørsystemet indbygges en referencemålecelle, der består af en platin- eller mix-oxid-tråd, der er indført elektrisk isoleret i rørsystemet, hvor der i en kort periode måles den galvaniske strøm, der går mellem tråd og røret i hvilket målecellen er monteret og hvor en faldende strøm over tid kan tages som udtryk for stigende effekt af korrosionsforebyggelsen. 2. Fremgangsmåde til at kontrollere virkningen af korrosionsforebyggelse i et efterfølgende rørsystem ifølge krav 1 kendetegnet ved at der fra referencemålecellen føres en elektrisk forbindelse I til et korrosionsbeskyttende elektrolyseanlægs ensretterenhed, hvor der med ikke vist elektronik sikres en reguleringsmulighed af elektrolyseanlægget, hvor anoden og/eller katoden er af aluminium, zink eller andet amfotert metal således at elektrolysestrømmen vil være konstant eller faldende, så længe den galvaniske strøm gennem referencecellen er faldende og omvendt hvis denne strøm stiger da at elektrolysestrømmen også stiger. 3. Fremgangsmåde til at kontrollere virkningen af korrosionsforebyggelse i et efterfølgende rørsystem ifølge foregående krav kendetegnet ved at nævnte referencemålecelle anvendes men at den måler virkningen af et kemikaliedoseringsanlæg og desuden kan indrettes til at sikre en korrekt dosering i forhold til behovet ved styring af doseringspumpe. 4. Fremgangsmåde til at kontrollere virkningen af korrosionsforebyggelse i et efterfølgende rørsystem ifølge foregående krav kendetegnet ved at en passende PTC modstand er indskudt i målekredsen med fysisk kontakt til rørsystemet, således at der kan kompenseres for temperaturforskelle i systemet.
