ABSTRACT:
In conventional water meters, there is not a proportion between the flow velocity of water flowing through the meter and the movement of the part that measures, i.e., the rotation of the turbine. That lack of proportionality may be a cause of error. This problem is solved by an electronic automatic correction system, which compares the measurement data with a data base stored in its memory, effects the necessary corrections and supplies the exact reading of the actual volume of water used. The meter is able to detect low water flow and water leakage.
