Arduino-based automated system for determining water flow consumption in open flow

Abstract

The article provides an overview of modern methods and devices for measuring water flow in open channels and natural watercourses, reflects the shortcomings and errors in their application. Considered the possibility of using the Arduino element base for creating an automated system for metering water consumption in an open stream and sending data via a Bluetooth module. Has been investigated the eventuality of using the pipe sensor YF-S201 for measuring the flow rate of liquid, in conjunction with the ultrasonic sensor of distance НС-SR04 for determining the level of water in the flow. The results of the experiment carried out on the basis of the laboratory stand "Hydraulic structures" in KSTU are presented. There were performed processing of the measurement results on the basis of the Arduino UNO board and a laptop, as well as remote data transmission and their visualization on a smartphone. The absolute and relative errors of the proposed system have been calculated.
