The Wireless Ultrasonic Waterflow Monitoring System is a system equipped with the capability
to measure water flow rate and detect water leakage. This is of particular importance because
water leakage is an unpleasant by-product of some water flow systems and it is to be avoided
almost all the time. The system is designed in such a way to ensure a proper display of flow rates
at various time intervals and compares these values at all times against a certain flow rate
threshold allowing for leakage detection. The data collected will then be interpreted by human
readable GUI application.
