Description
Brass Water Flow Sensor – Hall Effect NPN Pulse Output
The YF-B10 / ZJ-B5 Brass Water Flow Sensor is a heavy-duty Hall effect flow meter designed for accurate liquid flow measurement in water systems, irrigation, industrial pipelines, and DIY electronics projects. Available in Brass 1 inch (G1″, YF-B10) and Brass 3/4 inch (G3/4″, ZJ-B5) variants, these sensors deliver NPN pulse output compatible with Arduino, Raspberry Pi, and PLC systems, with a wide operating voltage of 3.5–24V DC and max pressure rating of 1.75 MPa.
Key Features
- Hall Effect Pulse Output – Magnetic rotor generates NPN pulses proportional to flow rate, enabling precise digital flow measurement without complex analog circuitry.
- Wide Voltage Compatibility – Operates on 3.5–24V DC, making it directly compatible with Arduino (5V), Raspberry Pi (3.3V), ESP32, and industrial PLC systems without voltage regulators.
- Two Size Options – Choose Brass G1″ (YF-B10) for 2–50 L/min on larger pipelines, or Brass G3/4″ (ZJ-B5) for 1–30 L/min on smaller lines and compact pump systems.
- Heavy-Duty Brass Body – Solid brass construction withstands pipeline pressure up to 1.75 MPa, far exceeding standard household water pressure in municipal supply systems.
- High Temperature Tolerance – Rated for liquids up to 100°C, suitable for hot water lines, solar water heaters, and industrial process monitoring.
- Standard G Thread Connection – G1″ and G3/4″ male thread fittings integrate directly with standard Pakistani plumbing, irrigation, and industrial pipe fittings.
- Low Power Consumption – Operating current under 15 mA keeps power draw minimal in battery-powered or solar remote monitoring systems.
- SM-3P Plug Connector – Pre-wired cable with standard 3-pin SM connector (Red = VCC, Yellow = Signal, Black = GND) for quick installation without soldering.
- +/- 5% Accuracy – Suitable for flow monitoring, consumption tracking, and automated valve control in irrigation and water management systems.

Applications
- Arduino & Raspberry Pi Projects – Direct NPN pulse output connects to digital input pins for DIY water meters, flow loggers, and smart irrigation controllers.
- Drip & Garden Irrigation – Monitor water consumption in drip lines, sprinkler systems, and farm irrigation networks for efficient water management.
- Water Dispenser & RO Systems – Track filtered water output in reverse osmosis units, water coolers, and dispensing machines.
- Solar Water Heater Monitoring – High temperature rating (up to 100°C) makes it suitable for hot water loop flow measurement in solar thermal systems.
- Industrial Pipeline Monitoring – 1.75 MPa pressure rating handles most industrial water and liquid process lines for real-time flow data acquisition.
- Automatic Pump Control – Pulse output triggers relay or motor controller to start/stop pumps based on flow thresholds, preventing dry running.
- Smart Home & Building Automation – Integrate with ESPHome, Home Assistant, or custom PLC for building water consumption dashboards and leak detection.
Wiring Guide
- Red Wire (VCC) – Connect to 3.5–24V DC positive supply.
