Description

The YFDN50 flow sensor utilizes a mechanical rotor coupled with a Hall effect transducer. As fluid passes through the sensor body, it spins the rotor; an embedded magnet triggers the Hall sensor, generating a corresponding digital pulse signal. This design provides a reliable, contactless method for measuring flow rate without impeding the fluid stream.

Engineered for durability, the sensor features a stainless steel shaft and is constructed to withstand water pressures up to 1.75 MPa. Its sealing ring and housing are designed for leak-proof operation, making it suitable for integration into water control systems, filling equipment, and monitoring applications where consistent, long-term performance is required.

Key Features

  • Hall effect sensing provides a clean, digital square wave pulse output signal.
  • Wide flow measurement range from 10 L/min to 200 L/min.
  • Durable construction with a stainless steel rotor shaft for minimal wear.
  • Designed to operate under water pressures up to 1.75 MPa.
  • Broad compatible voltage range (3.5-12V DC) for use with 5V and 3.3V logic microcontrollers.
  • RoHS compliant materials and manufacturing.
  • Integrated sealing prevents water ingress and ensures sensor longevity.
  • Simple installation with standard G2 (½ inch) threaded connections.

Applications

  • Flow rate monitoring and control in residential water heaters and dispensers.
  • Liquid dispensing and filling systems for vending machines and commercial equipment.
  • Water consumption data logging in IoT-based smart agriculture or building management.
  • Coolant flow monitoring in industrial machinery and process control loops.
  • DIY projects and prototypes requiring accurate liquid flow measurement with Arduino or Raspberry Pi.

Frequently Asked Questions

What is the output signal of the YFDN50 flow sensor?

The sensor outputs a digital square wave pulse signal via its Hall effect sensor. The frequency of this pulse is directly proportional to the flow rate, allowing you to calculate liters per minute by counting pulses over a known time interval.

What is the maximum system voltage and current draw?

The operating voltage range is 3.5 to 12 volts DC. At a 5V supply, the sensor draws a maximum of 15 mA. Ensure your microcontroller or PLC digital input pin can safely sink or source the sensor's output current.

How do I install and wire this flow sensor?

Install the sensor vertically in your water line using its G2 (½ inch) threaded ports, ensuring the flow direction arrow is correct. Wiring typically involves connecting the red wire to VCC (3.5-12V), black to GND, and the yellow (or signal) wire to a digital interrupt or counter pin on your microcontroller.

What is the maximum pressure and temperature this sensor can handle?

The sensor is rated for water pressures up to 1.75 MPa. Its operating temperature range is 0°C to 80°C, making it suitable for cold water and heated liquid applications like water heaters, provided the temperature stays within this limit.
