YF-S201 1-30L/Min Flow Meter/Water Flow Sensor Water Flow Control Water Flow Switch Flow Meter Counter Flowmeter（G1/2）

General description Lightweight and compact, the YF-S201 Water Flow Sensor is designed for easy installation. It features a durable stainless steel impeller shaft and a robust sealing structure that prevents leaks. This sensor is primarily used in water heaters, water machines, card machines, and various water filling and control equipment. Technical specifications Model: YF-S201 Color: Black Material: PVC Flow rate range: 1-30L/min Operating voltage range: DC 5~18V Lowest rated operating voltage: DC 4.5V-24V Maximum operating current: 15mA (5V DC) Load capacity: <10mA/=10mA (5V DC) Working temperature: <80°C/=80°C Working humidity range: 35%~90%RH (no frost) Allowing pressure: 1.75Mpa Storage temperature: -25~+80°C Saving humidity: 25%~95%RH Installation Mount vertically with no more than a 5-degree inclination. Usage When water flows through the rotor, it causes the rotor to roll, with speed variations corresponding to different flow rates. The Hall sensor outputs a corresponding pulse signal based on the rotor's speed. Other information Precautions: Avoid violent shocks and chemical erosion. Do not throw or hit the sensor. Cord connection: Red: positive (+); Yellow: signal output; Black: negative (-).
