Mechatronic System Design and Implementation for Liquid Level Measurement

Abstract

Liquid level measurement is used to determine the height or volumetric amount of liquid in a tank. The aim is to do maximum work using minimum energy. Different types of level measurement methods are used according to the places of use. The designed and implemented system is aimed to keep the liquid level in the tank constant at the desired value. The control of the system is provided by PID (Proportional Integral Derivative) control method using a microcontroller. 16F877A is used as the microcontroller. The software of the level control is written in C language. Updating the software and examining the effect of the desired parameters on the level control were carried out with microcontroller. The detection of the liquid level was made by means of optical sensors. The level control of the liquid in the tank was carried out by controlling the pump and valve with software. A mechanism has been placed that can be controlled manually in case of an emergency. Security control is provided both electrically and mechanically. The designed and implemented system is inexpensive and can be used easily in the industry. It will also provide great benefits in electrical, electronics and mechatronics education.

Sıvı seviye ölçümü için mekatronik sistem tasarımı ve uygulaması

Abstract

Sıvı seviye ölçümü, bir depoda bulunan sıvının yüksekliğinin veya hacimsel miktarının belirlenmesi amacıyla kullanılır. Amaç minimum enerji kullanılarak maksimum iş yapmaktır. Tasarlanıp uygulanan sistem ile depodaki sıvı seviyesi istenilen değerde sabit tutmak hedeflenmektedir. Sistemin kontrolü mikrodenetleyici kullanılarak PID (oransal-integral-türevsel) kontrol metodu ile sağlanmıştır. Mikrodenetleyici olarak 16F877A kullanılmıştır. Sıvı seviyesinin algılanması optik sensörler vasıtasıyla yapılmıştır. Depo içinde bulunan sıvının seviye kontrolü; yazılım sayesinde pompa ve valfin kontrol edilmesiyle gerçekleştirilmiştir. Herhangi bir acil durum anında manuel olarak kontrol edilebilecek düzenek yerleştirilmiştir. Tasarımı ve uygulaması yapılan sistem ucuz ve endüstride kolaylıkla kullanılabilecek düzeydedir. Ayrıca, elektrik, elektronik ve mekatronik eğitiminde büyük faydalar sağlayacaktır
