Brand: HALJIA Model: YF-S201 Color: Black Material: PVC Water flow sensor consists of a plastic valve body, a water rotor, and a hall-effect sensor. When water flows through the rotor, rotor rolls. Its speed changes with different rate of flow. The hall-effect sensor outputs the corresponding pulse signal. Application: Mainly used for water heater, water machine, card machine, various types of filling equipment and water control device Features: Light weight, small size, easy to install. Inlaid with stainless steel impeller shaft, durable wearable. Seal Ring with the upper and lower force structure never leaks. Precautions: Non-violent shock, and chemical erosion. Non-throwing or hitting. Mounted vertically, should not exceed 5 degrees inclination. Temperature of Medium should not exceed 120'C Cord Connection: Red: Positive(+);Yellow: Signal output;Black: Negative(-) Specification: The lowest rated working voltage: DC4.5 5V-24V. Maximum operating current: 15 mA (DC 5V). Working voltage range: DC 5~18 v. Load capacity: ,<10mA / =10mA (DC 5V). Work temperature: <80'C/ = 80'C Work humidity range: 35%~90%RH (no frost) Allowing pressure: pressure 1.75Mpa Storage temperature: -25~+80'C Save humidity: 25%~95%RH Flow Range :1-30L / min Dimensions: 2.44 in x 1.42 in x 1.34 in (6.2 cm x 3.6 cm x 3.4 cm) Weight: 1.76 oz (50 g) Frequency: F=7.5*Q(L/Min) ; Error: ±2% Taking a example of the flow rate of 1L/min, that is, 7.5 * 1 * 60 is equal to the pulses output by 1 liter of water. Voltage: 3.5-24VDC, current can not exceed 10mA, output 450 pulses after flowing one liter of water. That is, frequency calculation = constant 7.5 * unit flow (L/min) * time (seconds) Flow range: 1-30L/min Packing List: 1 x Water flow sensor
