Abstract

Kinerja komponen sistem perpipaan, seperti valve, sangat dipengaruhi oleh fenomena Head Loss akibat gesekan aliran yang dapat menyebabkan inefisiensi energi, di mana keterbatasan alat uji komersial yang mahal dan tidak fleksibel mendorong kebutuhan akan solusi yang lebih ekonomis dan akurat. Penelitian ini bertujuan untuk merancang bangun sistem monitoring flow dan pressure yang terintegrasi pada alat pengujian valve untuk menganalisis karakteristik aliran fluida secara presisi, yang dirancang untuk dapat menyajikan dan menyimpan data secara real-time guna mengevaluasi pengaruh variasi bukaan valve dan Flowrate terhadap performa sistem. Metodologi penelitian menggunakan pendekatan eksperimental dengan sebuah globe valve tipe quick-opening yang digerakkan motor sebagai objek uji. Sistem akuisisi data memanfaatkan mikrokontroler Arduino Uno yang terhubung dengan satu sensor aliran (YF-B10) dan tiga sensor tekanan (WisNER WPT-83G-E2G4). Seluruh data pengukuran dan hasil kalkulasi seperti Pressure Drop, pressure loss, dan Head Loss ditampilkan dan direkam melalui Human Machine Interface (HMI) berbasis LabVIEW. Hasil penelitian menunjukkan sistem yang dibangun berhasil memonitor dan merekam data dengan akurasi tinggi (akurasi sensor flow 97,12% dan sensor pressure di atas 97,6%). Analisis data mengonfirmasi karakteristik quick-opening pada valve yang diuji, di mana Flowrate meningkat tajam pada bukaan awal dan cenderung stabil pada bukaan di atas 70%. Terbukti bahwa Pressure Drop berbanding terbalik dengan bukaan valve, menurun secara signifikan dari 17,65 psi pada bukaan 10% menjadi 3,00 psi pada bukaan 100%. Efek histeresis yang teramati sangat kecil, menandakan kinerja valve yang konsisten. Dengan demikian, sistem ini menyajikan solusi inovatif yang valid untuk optimasi pengujian valve, evaluasi efisiensi energi, dan pengembangan sistem perpipaan di industri.

The performance of piping system components, such as valves, is significantly affected by the Head Loss phenomenon due to flow friction, which can lead to energy inefficiency, while the limitations of commercial testing equipment, which is often expensive and inflexible, drive the need for a more economical and accurate solution. This research aims to design and build an integrated flow and pressure monitoring system for a valve testing apparatus to precisely analyze fluid flow characteristics, designed to present and store data in real-time to evaluate the influence of valve opening and Flowrate variations on system performance. The research methodology employs an experimental approach with a motorized quick-opening globe valve as the test object, utilizing an Arduino Uno microcontroller, one flow sensor (YF-B10), and three Pressure Sensors (WisNER WPT-83G-E2G4). All measurement data and calculated results, such as Pressure Drop, pressure loss, and Head Loss, are displayed and recorded through a LabVIEW-based Human Machine Interface (HMI). The results show that the developed system successfully monitors and records data with high accuracy (flow sensor accuracy of 97.12% and Pressure Sensor accuracy above 97.6%). Data analysis confirmed the quick-opening characteristic of the tested valve, where the Flowrate increased sharply at initial openings and tended to stabilize above a 70% opening. It was proven that the Pressure Drop is inversely proportional to the valve opening, decreasing significantly from 17.65 psi at 10% to 3.00 psi at 100%. The observed hysteresis effect was minimal, indicating consistent performance. Thus, this system presents a valid and innovative solution for optimizing valve testing, evaluating energy efficiency, and advancing the development of industrial piping systems.
