One significant challenge encountered in the process industry pertains to the management of fluid levels within tanks and the transportation of fluids between them. The focus of this study will be the examination of the interaction between two tanks. Certain accidents occur as a result of individuals failing to exercise vigilance over specific physical entities. The resolution of this issue necessitates the utilisation of concepts pertaining to data communication. Certain firms utilise various types of networks such as RS485 and RS232. In contrast, these technologies significantly reduce the amount of distance data transmitted. This project aims to develop a device capable of retrieving data from remote input/output (I/O) locations through the use of Wi-Fi technology. The UDP protocol is utilised for wireless communication in this context. Wireless technology is employed to monitor the fluid levels of two interconnected tanks in the system. A wireless fidelity (Wi-Fi) transmitter node is responsible for receiving level data and subsequently performing data processing. Individuals who possess a smartphone or tablet device equipped with a wireless fidelity (Wi-Fi) connection are also able to access data. The level of the tank is periodically measured using a smartphone, and the resulting data is visually represented in a graph. The Simulink result was compared to the data that was collected on mobile devices to make sure they were the same thing. The utilisation of Wi-Fi as a means of transmitting data is advantageous due to its expeditious and precise nature.
