Water Flow Sensor YF-S401
EGP 250
See other suppliers →Description
This simple flow sensor is very similar to its big brother, the YF-S201, but has been optimized for lower flow rates and features a higher pulse per liter count. Inside the housing, a small pinwheel with an attached magnet is spun by passing water; as the magnet makes each revolution, a hall effect sensor inside the housing outputs a pulse on the yellow wire. This sensor is best suited for flow rates between 0.3 and 6 liters per minute and outputs 5880 pulses per liter (approximately 1 pulse per 0.17mL). The sensor has a barbed 7mm connection point on each side with an inner diameter of 4mm. A 6 mm hose is recommended Avoid unit contact with corrosive chemicals The unit must be installed vertically, tilted no more than 5 degrees Liquid temperature should be less than 120 C to avoid damage to unit Specifications: Model: YS-S401 Working Voltage: DC 5V~12V Maximum Working Current: 15mA @ 5V DC Flow Rate Range: 0.3~6L/min Inlet Water Pipe Diameter: 4mm Load Capacity: ≤10mA (DC 5V) Water Pressure: ≤0.8MPa Size: Connections: Red: Power In Black: Ground Yellow: Signal Output Applications: Water heaters Water vending machine Flow measurement device Automatic water dispenser Agriculture Food processing Coffee/Tea makers Water Management
