Saier HZ21WD Water Flow Sensor (1–30 L/min, 4.5–18V)
The Saier HZ21WD is a turbine-based water flow sensor module designed for precise liquid flow rate monitoring from 1 to 30 L/min. Operating on a wide 4.5–18V DC supply, it provides both analog and digital output signals for easy integration with microcontrollers (Arduino, Raspberry Pi, ESP32) and industrial PLCs.
Features
- Turbine-based sensing delivers accurate flow rate measurements with 5–8% accuracy.
- Wide operating voltage range (4.5–18V DC) ensures compatibility with 5V and 12V logic systems.
- Compact, durable housing designed for easy inline installation in tight spaces.
- Provides flexible analog or digital output signals for versatile project integration.
- Suitable for monitoring both liquids and gases, supporting a broad range of applications.

The Saier HZ21WD Water Flow Sensor employs a precision turbine mechanism to translate fluid velocity into a measurable electrical signal. As fluid passes through the sensor body, it spins an internal rotor, generating a Hall effect pulse train proportional to the flow rate. This signal is conditioned onboard for robust analog or digital output.
Constructed for reliable long-term operation, the sensor features a durable housing capable of withstanding working pressures up to 1.75 MPa. Its low power consumption (≤15mA) and wide input voltage tolerance make it suitable for both battery-powered IoT devices and mains-powered industrial control systems, ensuring stable performance across varying supply conditions.
