SEA YF-B1-S-SM G1/2 Inch Water Flow Sensor


The SEA YF-B1-S-SM Brass Water Flow Sensor is a high-quality flowmeter designed for precise measurement of liquid flow in automation, home appliances, and industrial control systems. Constructed with a durable brass body, this sensor is engineered to withstand high pressure, corrosion, and long-term operation in demanding environments. It features a G1/2 inch threaded interface, making it compatible with standard water pipe fittings. Using an internal hall-effect sensor, it generates digital pulses relative to the rate of water flow, ensuring fast, stable, and accurate signal output. Operating over a wide voltage range of 3.5V to 24V, and supporting a flow rate of 1–25 liters per minute, this sensor is ideal for integration with Arduino, ESP32, Raspberry Pi, and other controller boards. Whether used in water heaters, vending machines, smart irrigation systems, or liquid dispensing equipment, the SEA YF-B1-S-SM offers reliable performance and flexible integration for both DIY and professional automation needs.
