Water Flow Sensor with Barb Joint – 6mm Hose Flowmeter for Water Cooler & Coffee Machine, Leak-Proof Detection 0.3-6L/min Range

YF-S401 water flow sensor monitors liquid flow from 0.3 to 6L/min with precision. Designed for 6mm hose systems, this compact flowmeter detects inflow volume in water machines and filtration units. Its barb joint ensures secure tubing connection without leaksInstall this sensor at water inlet points to track flow rates. Connect red wire to positive, black to negative, and yellow for pulse signal output. Suitable for coffee makers, water coolers, and filtration systems. The plastic housing resists water pressure up to 1.75 MPaSpecification:Model: YF-S401Monitoring Range: 0.3-6L/minColor: WhiteSize: 58*35*27mm(2.28*1.38*1.06in)Wiring Method: Red +, Black -, Yellow For Signal Output (NPN Pulse Signal)Minimum Rated Operating Voltage: DC 3.5, 5V - 12VMaximum Operating Current: 15 mA (DC 5V)Operating Voltage Range: DC 5 - 18 VLoad Capacity: ≤ 10 mA (DC 5V)Operating Temperature Range: ≤ 80℃Operating Humidity Range: 35% - 90% RH (non-condensing state)Allowable Pressure Resistance: Water pressure below 1.75 MpaStorage Temperature: -25 - +80℃Storage Humidity: 25% - 95% RHPackage List:1 x Water Flow Sensor
