Water Flow Sensor - YF-B6 Flowmeter G3/4 1-30L/min 5-15V Brass
===============================================YF'B6 WATER FLOW SENSOR INFO===============================================MODEL: YF'B6 FlowmeterTHREAD SIZE: G3/4 (standard plumbing)FLOW RANGE: 130 L/minOPERATING VOLTAGE: 515 V DCOUTPUT: Pulse signal (frequency proportional to flow)BODY MATERIAL: Brass (durable, corrosion'resistant)SEALING: Rubber / EPDM or similar gasketWORKING PRESSURE: Up to ~23 MPa (varies by version)TEMPERATURE RANGE: ~080C (typical)----------------------------------------------- WHAT IT DOES:Measures **water flow rate** using a mechanical rotorinside the brass body. As water passes, the rotor spins.Each rotation generates a pulse via a hall effect sensor.Pulse frequency flow rate.----------------------------------------------- HOW IT WORKS: Water enters inlet pushes roController counts pulses calculates flowPulse Frequency Flow:Flow (L/min) = K Frequency (Hz)(K = calibration constant, usually ~7.5)Example: 450 Hz ~60 L/min (illustrative)----------------------------------------------- ELECTRICAL CONNECTION:Red VCC (515 V DC)Black GNDYellow/White Pulse Output (digital)----------------------------------------------- CHARACTERISTICS: **Linear response**: More flow = higher pulse rate **Brass body**: Strong, long'lasting **Compact**: Easy inline installation **Wide range**: 130 L/min suitable for many pumps **Low power**: Works with microcontrollers----------------------------------------------- KEY SPECIFICATIONS:Flow Range: 130 L/minThread: G3/4 maleVoltage: 515 V DCOutput Typ--------------------------- TYPICAL APPLICATIONS: Water dispensers Irrigation systems Pool/Spa flow monitoring Pump control & feedback DIY fluid monitoring Aquaculture & hydroponics----------------------------------------------- DESIGN & INSTALLATION NOTES: Install sensor **in horizontal pipe** with arrow direction Prevent air bubbles reduce signal noise Use proper sealing tape on threaded joints Place away from strong electrical no
