IoT Smart Water Measurement System

Description: IoT Smart Water Measurement System - the piezoelectric sensor enables acoustic leak detection within water distribution networks. By detecting high-frequency vibration and sound signatures generated by leaks, the system allows real-time monitoring, early fault identification, and improved water conservation. This supports smarter infrastructure management and reduces water loss. 

Why PUI Audio: This global company specializes in life-saving and water management solutions. Leveraging our strong relationship with the local representative, the customer agreed to evaluate PUI Audio’s piezo sensing products for acoustic leak detection. During testing, environmental noise interference and signal stability were identified as key challenges. Our engineering team delivered a customized shielded wire solution and validated performance against moisture exposure and corrosive environmental conditions typical in municipal water systems. The result was a reliable sensing solution optimized for accurate leak detection in real-world installations.

Product: The AB1290B-LW100-R is a high-frequency piezo bender suitable for vibration and acoustic sensing applications. With a 9 kHz resonant frequency, up to 30 Vp-p input capability, and a lightweight brass plate construction, it offers high sensitivity and fast response. In IoT-based water monitoring systems, it functions as an acoustic sensor capable of detecting subtle leak-induced vibrations in pipes, making it ideal for compact, energy-efficient smart water infrastructure devices.
