ARM Based Hybrid Measurement System Design for Liquid Level Measurement with High Accuracy under Vibrating Case

Abstract

In this study, the design and implementation of a 32-bit ARM microcontroller based measurement system which can measure the liquid level with an accuracy and resolution that have maximum 1% error level in liquid tanks under the mechanical vibrations produced by the actuators during their work is realized. It is aimed to prevent losses of sensor’s measurement accuracy over time and so preventing the erroneous results of the measurements by measuring the liquid level without contact and without adding any measuring material or device to the liquid in the tank. The measurement system is created by using hybrid method of ultrasonic, temperature and humidity sensors, and unlike conventional tactile liquid level measurement methods, it can measure the level of non-contact liquids such as fuel, chemical solutions, and it might be easily adapted to liquid tanks of different sizes and shapes. Since the of the sound waves sent from the ultrasonic sensor can change with the temperature and humidity, for calculation of the actual speed of the sound waves, taking the measurement data obtained from temperature, humidity sensors into consideration. Thus, the accuracy of liquid level measurement is increased by using this hybrid sensor consisting of ultrasonic, temperature and humidity sensors. Liquid levels are measured in 3 different vibration intensity as low, medium and high, respectively and the measurement error that might be caused by mechanical vibrations is reduced by using different iterations of the median filter, and the remaining measurement error is eliminated by using data such as liquid level measurement and liquid tank vibration intensity in a regression analysis. The final liquid level measurement result after regression model is transferred from 32-bit ARM based microcontroller to an android application via a Wi-Fi module wirelessly.
