Design of testbed system based on infinite cycle algorithm for liquid flowmeter calibration

Öz

In this study, a small-volume, low-cost and high-accuracy microcontroller-based testbed system based on infinite cycle algorithm is designed for the desired time calibration of liquid flowmeters. The fundamental principle of this system is based on weighing the amount of liquid without interrupting the liquid flow. The hardware of the system consists of mechanical and electronic modules including microcontroller, TFT display, load cell, thermocouple, tank, pump, etc. An algorithm for the designed infinite cycle calibration system is developed and microcontroller software is coded in C++. The weight data of the liquid obtained with the load cells are processed in the microcontroller depending on time. As a result, the designed microcontroller-based system contributes to users and researchers by enabling the automatic testing and analysis of liquid flowmeters.

Öz

Bu çalışmada, sıvı akışölçerlerin istenen sürede kalibrasyonu için sonsuz çevrim algoritmasına dayalı küçük hacimli, düşük maliyetli ve yüksek doğruluklu mikrodenetleyici tabanlı bir test sistemi tasarlanmıştır. Bu sistemin temel prensibi, sıvı akışını kesmeden sıvı miktarını tartmaya dayanmaktadır. Sistem donanımı mikrodenetleyici, TFT ekran, yük hücresi, termokupl, tank, pompa vb. mekanik ve elektronik modüllerden oluşmaktadır. Tasarlanan sonsuz çevrim kalibrasyon sistemi için bir algoritma geliştirilmiş ve mikrodenetleyici yazılımı C++ dilinde kodlanmıştır. Yük hücreleri ile elde edilen sıvının ağırlık verileri ise zamana bağlı olarak mikrodenetleyicide işlenmektedir. Sonuç olarak bu çalışmada tasarlanan mikrodenetleyici tabanlı sistem, sıvı akışölçerlerin test ve analizlerinin otomatik olarak yapılmasında kullanıcılara ve araştırmacılara katkı sağlamaktadır.
