1.Introduce<\/strong><\/h2>\n\n\n\n

The SAIER Passive Water Flow Sensors employs advanced Wiegand sensor technology, leveraging a dual magnetic pole triggering mechanism to detect water flow. As water passes through the flow meter, the sensor is activated to generate and output electrical signals. The frequency or pulse count of these signals is directly proportional to the water flow rate, enabling highly accurate measurement and recording of actual water consumption.<\/p>\n\n\n\n

The key benefit of this design is its “passive” operation\u2014meaning it can function reliably without any external power supply. This simplifies installation and maintenance, eliminating the need for additional wiring or power sources. It also allows for real-time water flow monitoring, providing precise data for end-users and water management systems. This makes it an ideal solution for smart water management, energy-saving bathrooms, and high-reliability metering applications.<\/p>\n\n\n\n
