A fluid-flow detection system comprises a flow sensor configured to measure a flow rate of a fluid within a conduit, an energy harvester coupled to the flow sensor, and a wireless communications module coupled to the energy harvester such that the energy harvester is configured to generate electrical energy derived from the fluid flow, the wireless communications module is configured to transmit a wireless signal associated with the measured flow rate, and the wireless communications module transmits the wireless signal when energized by the energy harvester. |
