Description

The Saier HW06C water flow sensor utilizes a Hall-effect turbine mechanism to generate a digital pulse signal proportional to the flow rate passing through its chamber. This design provides a reliable and contactless method for measuring liquid flow, ensuring long-term durability and minimal pressure drop. The sensor’s output is a clean square wave, making it simple to interface with common digital input pins on development boards and industrial controllers.

Constructed with a robust plastic housing and brass threaded fittings, the sensor is rated for working pressures up to 1.2 MPa. Its low current consumption (≤15mA) and wide voltage input make it versatile for battery-powered or mains-powered systems. The integrated signal conditioning provides a defined high-level output (≥4.5V) and low-level output (≤0.5V) for reliable digital communication.

Key Features

  • Hall-effect turbine sensor delivers a digital pulse output proportional to flow rate.
  • Broad 4.5V to 18V DC input range supports flexible system integration.
  • Low power consumption with a maximum input current of 15mA.
  • Durable construction with brass fittings and a plastic housing for reliable in-line use.
  • Designed for low flow rate applications from 0.15 L/min to 1.5 L/min.
  • High insulation resistance (>100 MΩ) and dielectric strength (AC500V) for electrical safety.
  • Compact form factor facilitates installation in space-constrained environments.
  • Provides a direct interface for microcontrollers without requiring additional signal conditioning.

Applications

  • Flow rate monitoring in water dispensers, coffee machines, and vending machines.
  • Liquid consumption tracking in smart home and IoT-based water management systems.
  • Process control in small-scale industrial equipment and laboratory setups.
  • Water meter functionality for appliances like water heaters and filtration systems.
  • Irrigation system flow monitoring for agricultural and gardening applications.

Frequently Asked Questions

What is the output signal type of the HW06C flow sensor?

The HW06C provides a digital pulse output generated by an internal Hall-effect sensor. Each pulse corresponds to a specific volume of liquid passing through the turbine, allowing you to calculate the flow rate by counting pulses over time using a microcontroller's digital input pin.

What is the operating voltage range, and is it 5V Arduino compatible?

The sensor operates from 4.5V to 18V DC. It is fully compatible with 5V Arduino boards, as its output high-level voltage is ≥4.5V when powered at 5V. Ensure your power supply can provide the required ≤15mA current for stable operation.

How do I install and wire the HW06C water flow sensor?

Install the sensor in-line with your liquid pipe using its G1/4" brass threads. For wiring, connect the red wire to your positive supply voltage (4.5-18V), the black wire to ground, and the yellow (or green) wire to a digital input pin on your microcontroller to read the pulse output signal.

What liquids can this flow sensor measure?

This sensor is designed primarily for water and other low-viscosity, non-corrosive liquids. It is not recommended for use with viscous fluids, oils, or corrosive chemicals, as they may damage the internal turbine mechanism or affect measurement accuracy.

What is the accuracy and how do I calibrate it?

The sensor has a stated accuracy of 5% to 8%. Calibration involves determining the K-factor (pulses per liter) for your specific unit. Measure a known volume of water, count the pulses generated, and calculate the K-factor to use in your flow rate formula for accurate readings.
