Pozitif Deplasmanl\u0131 Ak\u0131\u015f Sens\u00f6rlerinin \u0130\u015flevselli\u011fini ve Uygulamalar\u0131n\u0131 Anlamak<\/h1>\n

\nPD ak\u0131\u015f \u00f6l\u00e7erler olarak da bilinen pozitif yer de\u011fi\u015ftirmeli ak\u0131\u015f sens\u00f6rleri, petrol ve gaz, kimyasal i\u015fleme ve yiyecek ve i\u00e7ecek dahil olmak \u00fczere \u00e7e\u015fitli end\u00fcstrilerde \u00f6nemli bir bile\u015fendir. Bu cihazlar, bir boru hatt\u0131ndan ge\u00e7en bir s\u0131v\u0131n\u0131n hacmini veya ak\u0131\u015f h\u0131z\u0131n\u0131 \u00f6l\u00e7mek i\u00e7in tasarlanm\u0131\u015ft\u0131r. Hacmi bilinen b\u00f6lmeleri tekrar tekrar s\u0131v\u0131yla doldurup bo\u015faltma prensibiyle \u00e7al\u0131\u015f\u0131rlar. Daha sonra toplam ak\u0131\u015f, bu b\u00f6lmelerin doldurulma ve bo\u015falt\u0131lma say\u0131s\u0131na g\u00f6re hesaplan\u0131r.<\/p>\n

Pozitif yer de\u011fi\u015ftirmeli ak\u0131\u015f sens\u00f6rlerinin i\u015flevselli\u011fi, onlar\u0131n benzersiz tasar\u0131m\u0131na ve \u00e7al\u0131\u015fmas\u0131na dayan\u0131r. Sens\u00f6r ak\u0131\u015f\u0131 engelleyen bir odadan olu\u015fur. Bu odan\u0131n i\u00e7inde rotor ad\u0131 verilen d\u00f6nen veya ileri geri hareket eden bile\u015fenler bulunur. S\u0131v\u0131 b\u00f6lmeye akarken, rotorlara do\u011fru iterek onlar\u0131n hareket etmesine veya d\u00f6nmesine neden olur. Her d\u00f6n\u00fc\u015f belirli bir s\u0131v\u0131 hacmine kar\u015f\u0131l\u0131k gelir. Sens\u00f6r, d\u00f6n\u00fc\u015f say\u0131s\u0131n\u0131 sayarak i\u00e7inden ge\u00e7en s\u0131v\u0131n\u0131n hacmini do\u011fru bir \u015fekilde \u00f6l\u00e7ebilir.<\/p>\n

Pozitif yer de\u011fi\u015ftirmeli ak\u0131\u015f sens\u00f6rlerinin temel avantajlar\u0131ndan biri, y\u00fcksek d\u00fczeyde do\u011fruluktur. Di\u011fer tipteki ak\u0131\u015f \u00f6l\u00e7erlerden farkl\u0131 olarak PD ak\u0131\u015f sens\u00f6rleri s\u0131v\u0131n\u0131n s\u0131cakl\u0131k, bas\u0131n\u00e7 veya viskozitesindeki de\u011fi\u015fikliklerden etkilenmez. Bu, onlar\u0131 viskoz s\u0131v\u0131lar\u0131n veya de\u011fi\u015fen fiziksel \u00f6zelliklere sahip s\u0131v\u0131lar\u0131n ak\u0131\u015f\u0131n\u0131 \u00f6l\u00e7mek i\u00e7in ideal k\u0131lar. \u00dcstelik \u00e7ok d\u00fc\u015f\u00fckten \u00e7ok y\u00fckse\u011fe kadar geni\u015f bir ak\u0131\u015f h\u0131z\u0131 aral\u0131\u011f\u0131n\u0131 i\u015fleyebilirler, bu da onlar\u0131 farkl\u0131 uygulamalar i\u00e7in \u00e7ok y\u00f6nl\u00fc k\u0131lar.<\/p>\n
