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.Claim 1. A method for controlling the effect of corrosion prevention in a subsequent pipe system characterized by incorporating in the pipe system a reference measuring cell consisting of a platinum or mix oxide wire electrically insulated in the pipe system, where a period, the galvanic current passing between the wire and the tube in which the measuring cell is mounted is measured and where a decreasing current over time can be taken as an expression of the increasing effect of the corrosion prevention. A method of controlling the effect of corrosion prevention in a subsequent pipe system according to claim 1, characterized in that an electrical connection I is fed to the rectifier unit of a corrosion protection electrolysis system, whereby the electrolysis plant, with the anode and / or control, is provided with a control possibility. the cathode is of aluminum, zinc or other amphoteric metal so that the electrolysis current will be constant or decreasing as long as the galvanic current through the reference cell is decreasing and vice versa if this current increases then the electrolysis current also increases. A method of controlling the effect of corrosion prevention in a subsequent pipe system according to the preceding claim, characterized in that said reference measurement cell is used, but it measures the effect of a chemical dosing system and can furthermore be arranged to ensure a correct dosage in relation to the need for control of the dosing pump. Method for controlling the effect of corrosion prevention in a subsequent pipe system according to the preceding claim, characterized in that a suitable PTC resistor is inserted into the measuring circuit with physical contact to the pipe system, so that temperature differences in the system can be compensated.
