Study on automatic water level detection process using ultrasonic sensor

Abstract

Currently, we live in a world where all fields are developing very rapidly. In particular, the field of water management is developing day by day, and the water supply system is being intelligent automated. Nevertheless, mechanical means and human labor are used to monitor the water level in many water management facilities of our region. This situation causes many problems in the automatic management of the system. In this article, we will consider the process of automating the measurement and control of water level, that is, an automated system that helps to know when the water in the tank is full or empty. In the automation of this system, an ultrasonic sensor that meets the requirements of the time was used. The working principle of ultrasonic sensors is based on the movement of ultrasonic waves over time. The analysis of the results of this experiment showed that the water level measurement and control system did not make more than 1.5% error in different values of the water level. This situation showed that the developed system can be effectively used in all water level control facilities.

Water level identification with laser sensors, inertial units, and machine learning

“…Water level measurement through ultrasonic sensors has been employed in different applications. Some works addressed level measurement and control in water tanks, such as Gondkar et al [38], Choubey et al [39], Jan et al [40] and Djalilov et al [41]. A more critical environment was addressed by Sasikala et al [42], which proposed safeguard methodologies for dams and reservoirs based on water level measurement through ultrasonic sensors, with results showing a low error rate and short data transmission latency.…”

“…Among them, two were associated with the LiDAR sensor (i.e., IR h and IR s ), one with the ultrasonic sensor (i.e., U S h ), and six with the IMU (i.e., a x , a y , a z , g x , g y , and g z ). The inclusion of the ultrasonic sensor in our comparisons was motivated by its widespread usage as a non-immersive sensor for water level identification [53,54,41], with accurate results on controlled environments. For this reason, we employed it as a reference to evaluate the results of our models.…”

Study of the interdigital electrode sensor at resonance frequency during water transition

“…The various types of liquid-level monitoring techniques are applied for different applications. Some popular detectors for liquid level measurements are the pressure sensor [18,19], ultrasonic sensor [15,20], optical sensor [21,22], capacitor sensor [23][24][25][26], etc. Every different sensor has its advantages and disadvantages due to its properties.…”
