Automatic Calibration for Residential Water Meters by Using Artificial Vision

The present work addresses the problem of automated calibration system for residential water meters, by using artificial vision. The project consists of a closed water flow circuit powered by a low-power pump; the data from water meter is taken by the computer using a USB camera; a calculation is made based on the time it takes to fully rotate the smaller-scale needle of the meter to determine the water flow in real time. At the same time, the actual flow data of the reference standard element, which is a rotameter, is obtained by a second camera. These values are compared to calculate an error that determines the adjustment action on the water meter.
