SEA YF-G1 Water Flow Sensor G1″ 1–100L/min Turbine Flowmeter 3.5–24V

Description �� SEA YF-G1 Water Flow Sensor G1″ Turbine Flowmeter 2–100 L/min | AuscomTech The SEA YF-G1 Water Flow Sensor is a turbine-based Hall-effect flowmeter designed for accurate and repeatable water flow measurement in monitoring, control, and automation systems. It outputs an NPN pulse signal proportional to flow rate, making it easy to interface with microcontrollers, PLCs, data loggers, and industrial controllers for real-time water usage tracking and automated control. With a standard G1-inch (DN25) male threaded interface, wide operating voltage range, and robust operating temperature capability, the YF-G1 is well suited to residential, commercial, and industrial water measurement applications. ⭐ Key Features ��️ Turbine-Based Hall Flow MeasurementInternal turbine and Hall sensor generate a stable pulse signal proportional to water flow. �� Wide Flow Measurement RangeMeasures water flow rates from 2 to 100 litres per minute, covering both moderate and high-flow systems. �� Standard G1″ (DN25) Thread InterfaceMale G1-inch thread allows easy installation into common plumbing and pipework. ⚡ Wide Operating Voltage RangeOperates from DC 3.5–24V, compatible with 3.3V, 5V, and industrial control systems. �� Flexible Mounting OrientationCan be installed vertically or horizontally without affecting operation. ��️ Wide Operating Temperature RangeRated for environments from -40°C to 80°C. �� Durable Plastic HousingLightweight black plastic body suitable for clean water applications. �� Technical Specifications Model: SEA YF-G1Sensor Type: Turbine Hall-effect water flow sensorNominal Size: DN25Thread Size: G1″ maleFlow Range: 2–100 L/min (max)Output Signal: NPN pulse outputPulse Formula:F = 1.08 × Q (Q = L/min) ±5�curacy: ±3%Operating Voltage: DC 3.5–24VOperating Temperature: -40°C to 80°CMaximum Pressure: < 1.75 MPaMeasured Medium: Clean waterHousing Colour: Black Wire Connections:• Red: V• Black: GND• Yellow: Pulse signal output (NPN) ⚠️ Important Notes • Flow direction must match the arrow on the sensor body• Suitable for clean water only (no debris, particles, or viscous fluids)• Install a filter upstream if water quality is poor• Output is a pulse signal and requires frequency counting in software• Do not exceed rated pressure or flow limits �� Compatible With • Arduino (Uno, Mega, Nano)• ESP32 / ESP8266• Raspberry Pi (with suitable input conditioning)• STM32 microcontrollers• PLC digital input modules• Data loggers and flow controllers• 3.3V and 5V logic systems (with appropriate pull-ups) ⚙️ Typical Applications • Water usage monitoring• Irrigation and garden watering systems• Pump flow verification• HVAC and cooling water systems• Industrial water management• Building automation and control• DIY and embedded flow measurement projects �� Package Includes • 1 × SEA YF-G1 G1″ Water Flow Sensor
