Abstract

Bufferinnsats (100) anbragt l et hukommelsemålesystem sitt bufferkammer (22). Bufferinnsatsen (100) har en forlenget Innløpsrørledning (130) med redusert diameter som er festet til bufferkammerets (22) åpning. Innløpsrørledningen (130) anvender kaplllarvlrknlngen for å forhindre at brønnborefluld går Inn l bufferkam- meret (22). Innløpsrørlednlngen (130) tvinger inflltrerende fluider å gå opp nær kammerets (22) topp i stedet for kammerets (22) bunn. Innsatsen (100) har dessuten en forlenget krøllet kapillarrør (104) som tillater en begrenset fluidkommunlkasjon mellom kammeret (22) og transduseren (32). Inngangen til det krøllede kapillarrøret (104) er anordnet nær bunnen til bufferkammeret (22) for derved å tvinge Inflltrerende fluider å utbrette seg nedover mot den mer vlskøse slllkonoljen. Tester har vist at systemet l stor grad reduserer kontakten med transduserens (32) komponenter av Inflltrerende brønnboreflulder.
