Automatic Calibration for Residential Water Meters by Using Artificial Vision
- 10 Downloads
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.
