Taylor, Michigan Patent of the Year – 2024/2025
Masco Corporation has been awarded the 2024/2025 Patent of the Year for its innovative advancement in water quality monitoring. Their invention, detailed in U.S. Patent No. 11953459, titled ‘Multi-functional water quality sensor’, introduces a compact sensor capable of simultaneously measuring key water parameters, including temperature, flow rate, pH, oxidation-reduction potential (ORP), and conductivity.
This sensor integrates multiple sensing capabilities onto a single, electrically non-conductive substrate with conductive traces. It features a temperature sensor circuit and a heater circuit, where the dissipation of heat correlates with the water’s flow rate. Additionally, it includes three electrodes arranged in concentric circles to accurately assess the water’s acidity, ORP, and conductivity. This design allows for real-time, comprehensive water quality analysis in various applications.
The compact and integrated nature of this sensor simplifies installation and maintenance, making it ideal for use in spas, pools, and other water systems where monitoring multiple parameters is essential. By consolidating several sensing functions into one device, it reduces the need for multiple separate sensors, thereby lowering costs and improving efficiency.
Masco Corporation’s development represents a significant step forward in water quality monitoring technology. This multi-functional sensor offers a streamlined solution for maintaining safe and healthy water conditions, with potential applications extending beyond recreational water systems to industrial and environmental monitoring.
