YF-S201 Water Flow Sensor 4 in Hall Flowmeter DN15 Water Flow Sensor Switch 1-30L min Counter Sensor Control 1/2'' Flow Meter

Features:1. Using high-quality materials, the quality is guaranteed2. Use Imported Hall Vision3. Good sealing and no water leakage4. The magnet is isolated by the plastic shell, which has the function of preventing rust and iron slag from being attracted by the magnet, and there are stainless steel beads on the top and bottom. The product life is increased by two-thirds5. Wide applicationparameter:Model: YF-S201Interface size: 4 points (G1/2)Operating voltage range: DC5 ~ 15VInner/Outer Diameter: 10.9mm/20mmThread length: 14.5mm12.5mmMaterial: NylonWater pressure resistance: ≤1.75MPaOutput pulse high level: >DC4.7V (input voltage DC5V)Output pulse low level: Insulation resistance: >100MQFlow range: 1～30L/MINAirtightness: Close each hole, add 1.7Mpa water pressure test for 1 minute without leakage and deformationFlow pulse characteristics: F= (7.5*Q) error≤3%Instructions for use:1. In order to prevent particles and debris from entering the sensor, a filter must be installed at the water inlet of the sensor;2. The installation of the water flow sensor should be inside the equipment or indoors. Do not expose it to harsh environments such as outdoor or humid and high temperature for a long time. The installation of the water flow sensor must avoid vibration and shaking environments and applications, so as not to affect the measurement of the sensor. precision;3. When the magnetic material or the material that generates magnetic force on the sensor approaches the sensor, its characteristics may change;4. Do not disassemble the water flow sensor without authorization to prevent damage;5. The sensor of this structure has not been used, and it may be uncomfortable when it is used for direct replacement;Wiring:Red IN is connected to the positive poleYellow IN signal output lineBlack GND to negative polePackage list:Water flow sensor*1
