Ultrasonic Flow Meters and Microcontrollers for Precise Water Management with 6.45% Error Margin

Abstract Water management is crucial for human life, and precise measurement instruments are necessary to ensure efficient utilization. This study aimed develop a water usage system using ultrasonic flow meters microcontrollers. The results were displayed on screen sent via modbus remote devices. To validate the accuracy of system, comparison between manual was conducted, showing an error value 6.45%. implication this potential use consumption control transmission over long distances, contributing sustainable management.
