Problem statement: Although the traditional metering system and method for controlling flow is generally safe, reliable and robust, it does suffer certain drawbacks, such as limited accuracy and the ability to implement complex reactive rate designs. Hence, there is a need for a circuit and method of increasing metering accuracy, as well as the position control accuracy for variable flow rates, without further reliance on mechanical tolerances. An essential component for an electronic meter is a database and method of communication to obtain the required measurements and to program the meter for any additional needed values. Flexibility is added to such meters by using wireless communication circuits and protocols, which will enable reading of multi-devices from the same source point. Approach: To collect data, critical quality of service and carry out analysis, wireless flow meter reading system is designed, tested and implemented. The hardware and software in the designed system work together, to wirelessly receive readings from meters and then process it in order to obtain an accurate reading for the measured flow. The system makes use of modern communication algorithms and techniques. Also, the system allows for history tracing and analysis. The interfacing hardware uses two-way wireless optical interface to flow meter device. Results: The Hardware and Communication Protocol tested successfully and provided sufficient and accurate data for flow measurements analysis, presented in this research. Conclusion: Such hardware-software arrangement is considered a core for mobile meter reading and control with possibility to add intelligent security algorithms.
