The AFD4040 Series is a vortex water flow sensor based on the principle of Von Karman vortices. When a certain volume of fluid flows around the spoiler column under certain conditions, double row linear vortices with opposite rotating directions and regular arrangement will periodically form on both sides of the spoiler column, forming a Karman vortex street. The sensor senses the frequency of the vortex flow through the internal chip, thereby measuring the liquid flow rate flowing through the pipe. The sensor features long life, resistance to contamination, high accuracy, fast response and no drift, making it ideal for demanding and cost-sensitive applications.

  1. Measurement Range: Available in 2–16 L/min, 5–40 L/min, and 10–100 L/min options.
  2. Temperature Range: Operates within a liquid temperature range of 0 to 90°C.
  3. Flow Accuracy: Offers a flow accuracy of <±3.0% F.S.
  4. Temperature Accuracy: Maintains temperature accuracy of ±5% F.S. max.
  5. Repeatability: Provides repeatability of <2.0%.
  6. Durable Materials: Constructed from PPS and SUS304 stainless steel for liquid contact.

Package includes: 1 x Asair AFD4040 Series Vortex Liquid Flowmeter

Setup Guide

1
Identify the pins
Locate VCC (power), GND (ground), and data pins (SDA/SCL for I2C, MOSI/MISO for SPI, or TX/RX for UART). Refer to the pinout diagram on the product page.
2
Wire to your microcontroller
Connect VCC to 3.3V or 5V (check the module spec), GND to GND, and data pins to the appropriate GPIO pins on your Arduino or Raspberry Pi.
3
Install libraries
In Arduino IDE, go to Sketch → Include Library → Manage Libraries and search for the sensor library. Install the recommended version.
4
Upload example sketch
Open File → Examples → [library name] → Basic Example. Upload to your board and open Serial Monitor to view output.
5
Calibrate if needed
Some sensors (temperature, humidity, distance) may need a short warm-up period or calibration. Run the calibration sketch if provided.
