Description

The Saier HZ06W 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 pulse frequency proportional to the flow rate. This signal is conditioned internally for stable analog or digital output.

Constructed for reliability, the sensor features a robust housing capable of withstanding working pressures up to 1.20 MPa. Its electrical design includes high insulation resistance (>100 MΩ) and dielectric strength (AC500V, 50Hz), ensuring safe operation in various liquid monitoring environments. The sensor is suitable for integration into automated water systems, IoT devices, and industrial process controls.

Key Features

  • Precision turbine flow sensor with a measurement range of 0.25–2.5 liters per minute.
  • Broad DC supply voltage compatibility from 4.5V to 18V for use with 5V and 12V logic systems.
  • Low quiescent current draw (≤15mA) optimizes power consumption for battery-powered applications.
  • Durable mechanical construction ensures long-term performance and resistance to water pressure.
  • High-level output voltage ≥4.5V and low-level output ≤0.5V provide clean signal interfacing.
  • Designed with high insulation resistance (>100 MΩ) for enhanced electrical safety.
  • Compact form factor facilitates installation in space-constrained plumbing or equipment.
  • Versatile output options (analog/digital) support direct connection to microcontrollers and data loggers.

Applications

  • Precise flow monitoring in compact water dispensers, coffee machines, and beverage vending systems.
  • Water usage tracking and leak detection in residential and commercial IoT-based smart water meters.
  • Process control and dosing systems in laboratory equipment, medical testing devices, and chemical analyzers.
  • Coolant flow rate monitoring in industrial machinery, 3D printers, and laser engraving systems.
  • Irrigation flow management and nutrient solution dosing in automated hydroponic and agricultural setups.

Frequently Asked Questions

What is the operating voltage range for the Saier HZ06W sensor?

The Saier HZ06W Water Flow Sensor operates on a wide DC voltage range from 4.5V to 18V. This makes it directly compatible with common 5V microcontroller systems like Arduino, as well as 12V industrial or automotive power supplies, without requiring an additional voltage regulator.

How do I interface this flow sensor with an Arduino or Raspberry Pi?

The sensor provides both analog and digital (pulse) output options. For digital reading, connect the signal wire to a digital interrupt pin on your microcontroller to count pulses, which are proportional to flow rate. For analog reading, connect to an ADC pin. Ensure your code converts the signal based on the sensor's datasheet calibration for accurate flow calculation.

Can this sensor be used with liquids other than water?

While primarily designed for water, the turbine mechanism can handle other low-viscosity, clean, non-corrosive liquids and gases. For optimal accuracy and longevity, ensure the fluid is compatible with the sensor's internal materials (typically plastics and stainless steel) and does not contain particulates that could clog the turbine.

What is the accuracy and how do I calibrate the sensor?

The sensor has a stated accuracy of 5-8%. Calibration involves measuring the sensor's output (pulse frequency or analog voltage) against a known reference flow rate. You then establish a conversion factor (e.g., pulses per liter) in your control software. For highest precision, perform a multi-point calibration across your expected operating flow range.

What are the installation requirements and pressure limits?

Install the sensor inline with your liquid piping, ensuring flow direction matches the marked arrow on the housing. The maximum working water pressure is 1.20 MPa. Use appropriate thread sealant on the G1/2" (or similar) threads to prevent leaks. Avoid exposing the electrical connections to moisture.
