YF-XXWater Flow Sensor (Sea) YF-B2

The Water Flow Sensor features a durable plastic or brass body, a water rotor, and a hall-effect sensor integrated with a PCB electronics board.

Working Principle: As water flows through the sensor, it spins the rotor. The speed of the rotor varies with the flow rate, and this movement generates a magnetic field that activates the hall-effect sensor. The sensor then outputs a pulse signal corresponding to the flow rate.

This flow sensor is ideal for applications such as water dispensers and coffee machines, where precise monitoring of water flow is essential for efficient operation.

Water Flow Sensor (Sea) YF-B2 Flowmeter G1/2 1-25L/min Overview

The Water Flow Sensor (Sea) YF-B2 is a brass-bodied flowmeter with a G1/2″ threaded connection, designed to measure liquid flow rates between 1 and 25 L/min. It uses an integrated Hall-effect sensor to output digital pulse signals proportional to water flow, making it ideal for precise monitoring in compact fluid systems.

Key Features of Water Flow Sensor (Sea) YF-B2 Flowmeter G1/2 1-25L/min

• Durable brass construction with G1/2″ standard thread for easy integration
• Flow range from 1 to 25 L/min with ±5% accuracy (F = 11 × Q)
• Digital pulse output via Hall-effect sensor for accurate flow measurement
• Operates on 5–15 V DC with low current draw of 15 mA
• Supports both horizontal and vertical mounting positions
• Withstands up to 1.5 MPa pressure and temperatures from –40 °C to +80 °C
• Genuine product, fast shipping across India from Zbotic

Applications and Use Cases

• Flow monitoring in water dispensers and beverage machines
• Irrigation controllers for gardens and small farms
• Aquarium and pond water circulation systems
• Industrial cooling loops and heat exchangers
• Home or laboratory water purification setups
• Smart metering for tank level and flow control systems

How to Use Water Flow Sensor (Sea) YF-B2 Flowmeter G1/2 1-25L/min

Install the sensor inline with your water pipe using standard G1/2″ fittings, ensuring the arrow on the brass housing matches the direction of flow. Connect the red and black wires to a 5–15 V DC supply and the yellow output wire to a digital input on your controller. Count the pulses generated (F = 11 × Q) to calculate real-time flow rate, and secure all connections to prevent leaks.

Frequently Asked Questions

What pulse output does the YF-B2 provide per liter of water?

The sensor generates a pulse frequency F (in Hz) equal to 11 × Q (where Q is flow in L/min). At 1 L/min, you’ll receive approximately 11 pulses per second (660 pulses per minute), scalable up to 25 L/min.

Can I install this flowmeter in any orientation?

Yes. The YF-B2 supports both horizontal and vertical mounting. Ensure the flow arrow aligns with the direction of liquid movement, and secure the housing against vibration.

What temperature and pressure limits should I consider?

This brass flow sensor operates reliably from –40 °C up to +80 °C and can withstand pressures up to 1.5 MPa. It’s suitable for most domestic and light industrial water applications.
