Description

The Saier HZ16WA Water Flow Sensor utilizes a precision turbine mechanism to measure fluid flow. As liquid passes through the sensor body, it spins an internal rotor, generating a pulse frequency or analog voltage signal proportional to the flow rate. This electromechanical principle ensures reliable and repeatable measurements across its specified range.

Engineered for robust performance, the sensor features a housing capable of withstanding working pressures up to 1.75 MPa and offers high insulation resistance (>100 MΩ). Its wide 4.5-18V DC input range allows for direct compatibility with 5V and 12V logic systems commonly found in industrial control panels, IoT gateways, and DIY automation projects, providing a versatile solution for flow monitoring.

Key Features

  • Turbine sensor technology delivers consistent, repeatable flow measurements.
  • Broad 0.5-20 L/min measurement range accommodates diverse application needs.
  • Dual analog and digital output signals enable flexible interface with controllers.
  • Rugged construction ensures long-term reliability in both liquid and gas service.
  • Low power consumption design (≤15mA) optimizes energy use in continuous monitoring.
  • High-voltage insulation (AC500V, 50Hz) enhances electrical safety in wet environments.
  • Compact dimensions facilitate straightforward integration into existing piping or systems.

Applications

  • Residential and commercial water consumption monitoring and submetering.
  • Industrial process control for coolant, chemical, or irrigation flow regulation.
  • HVAC system water flow monitoring for heat exchangers and chillers.
  • DIY and educational projects for building smart aquaponics or hydroponics systems.
  • Liquid dispensing and batching systems in light industrial or laboratory settings.

Frequently Asked Questions

What is the operating voltage range for the HZ16WA flow sensor?

The sensor operates on a wide DC voltage range from 4.5V to 18V. This allows direct compatibility with common 5V microcontroller boards (like Arduino) and 12V industrial power supplies without requiring an additional voltage regulator.

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

The sensor provides both analog and digital output options. For digital interfacing, connect the signal wire to a digital input pin on your microcontroller to read pulse frequency. For analog voltage reading, connect it to an ADC pin. Ensure your power supply matches the sensor's voltage requirements.

Can this sensor be used with gases, or is it only for liquids?

Yes, the HZ16WA is suitable for measuring the flow of compatible gases as well as liquids. Ensure the gas is clean, dry, and non-corrosive to the sensor's internal materials. Calibration for gas flow may differ from liquid calibration.

What is the accuracy of the flow measurements?

The sensor has a stated accuracy of 5-8% across its 0.5 to 20 L/min range. For higher precision, user calibration against a known reference flow rate within your specific application is recommended to account for system-specific variables like viscosity and pressure.

What is the maximum pressure the sensor can withstand?

The HZ16WA is rated for a maximum working water pressure of 1.75 MPa. Do not exceed this pressure limit to prevent damage to the sensor housing and internal turbine mechanism. Ensure your plumbing connections are secure and rated for your system's operating pressure.
