1-30L/min G1/2 Hall Flow Meter Water Flow Sensor YF-S201

feature:1. This product is light and convenient in appearance, small in size and easy to install. 2. The impeller is inlaid with stainless steel beads, which is always wear-resistant. 3. The sealing ring adopts the upper and lower force structure, and never leaks. 4. Imported Hall elements are reinforced with waterproof apron silicone to prevent water ingress and never age. 5. All raw materials comply with ROHS testing standards. 6. The standard G1/2 threaded interface is easier and more secure to install.Precautions for use:●Severe impact and chemical corrosion are strictly prohibited. ●It is strictly forbidden to throw or collide. ●The medium temperature shall not exceed 120℃.

Lead method:Red IN is connected to positive pole, yellow OUT signal output line, black GND is connected to negative pole, green R temperature sensor (3950K 50K or 3950K 15K, please choose according to your own requirements) frequency: F=7.5*Q(L/Min), error: ±2% in 1L The flow rate per minute is column, 7.5 * 1 * 60 is equal to the number of pulses output by 1 liter of water. Voltage: 3.5-24VDC, current cannot exceed 10mA, output 450 pulses after flowing through one liter of water, that is, frequency calculation = constant 7.5*unit flow (L/min)*time (seconds) flow range: 1-30L/minTechnical Parameters:
