Description

The Saier HW06K Water Flow Sensor employs a precision turbine mechanism to translate fluid velocity into a measurable electrical signal. As liquid passes through the sensor body, it spins an internal rotor, generating a Hall effect-based pulse output proportional to the flow rate. This design ensures reliable and repeatable measurements across its specified range.

Engineered for robust performance, the sensor features a durable housing capable of withstanding working pressures up to 1.20 MPa. Its electrical isolation is rated with an insulation resistance greater than 100 MΩ and a dielectric strength of AC 500V at 50Hz, making it suitable for a variety of embedded and industrial control applications where signal integrity and safety are paramount.

Key Features

  • High-accuracy turbine flow sensor with a measurement range of 0.3 to 3.5 liters per minute.
  • Broad DC input voltage compatibility from 4.5V to 18V, ideal for 5V and 12V system architectures.
  • Dual-output capability: digital pulse signal and analog voltage output for maximum application flexibility.
  • Compact and lightweight form factor designed for straightforward inline installation.
  • Durable construction ensures long-term reliability in both liquid and compatible gas flow monitoring.
  • Low power consumption, drawing ≤15mA during operation.
  • High electrical isolation (>100 MΩ) for enhanced system safety and noise immunity.

Applications

  • Precise flow monitoring in water dispensers, coffee machines, and beverage vending systems.
  • Liquid consumption measurement for smart home automation and IoT-based water management.
  • Flow rate verification in medical diagnostic equipment and laboratory analyzers.
  • Process control and cooling loop monitoring in industrial machinery and agricultural irrigation systems.

Frequently Asked Questions

What is the output signal type of the Saier HW06K sensor?

The HW06K provides dual output options. It generates a digital pulse signal where the frequency is proportional to the flow rate, suitable for direct microcontroller input. It also offers an analog voltage output that varies with flow, providing flexibility for different data acquisition systems or ADCs.

What is the maximum pressure this flow sensor can handle?

The sensor is rated for a maximum working water pressure of 1.20 Megapascals (MPa). Exceeding this pressure limit may damage the internal turbine mechanism or housing. Ensure your system's operating pressure stays within this specification for reliable and long-term operation.

Can this sensor be used with microcontrollers like Arduino?

Yes, the HW06K is highly compatible with Arduino and similar development boards. The digital pulse output can be connected directly to a digital interrupt pin to count pulses per unit time, which can then be converted to a flow rate. The wide 4.5-18V operating voltage range makes it easy to power from common 5V or 12V sources.

Is the sensor suitable for measuring gas flow, or only liquids?

While primarily designed for water and similar liquids, the manufacturer specifies compatibility with certain gases. However, accuracy and performance may vary with gas density and viscosity. For critical gas flow applications, verify the sensor's calibration and performance under your specific gas conditions.
