Saier HZ21FA Water Flow Sensor (1–30 L/min) - DC 4.5-18V
The Saier HZ21FA is a turbine-based water flow sensor module compatible with 3.3V/5V logic systems like Arduino, Raspberry Pi, and ESP32. It provides precise flow rate monitoring from 1 to 30 L/min with analog or digital pulse output for industrial, home automation, and IoT fluid management projects.
Features
- Turbine-based flow sensing with 5-8% accuracy for reliable liquid and gas measurement.
- Wide operating voltage range from DC 4.5V to 18V, with low current draw ≤15mA.
- Robust construction rated for working water pressures up to 1.75 MPa (≈250 psi).
- Provides both analog voltage and digital pulse output for flexible system integration.
- Compact form factor for easy installation in confined plumbing or machinery spaces.

The Saier HZ21FA employs a precision turbine rotor to measure fluid flow. As liquid or gas passes through the sensor body, it spins the turbine, generating a corresponding digital pulse frequency or analog voltage signal proportional to the flow rate. This electromechanical principle ensures stable, repeatable measurements across its specified range.
Designed for integration into control systems, the module features a wide 4.5-18V DC input range, making it compatible with common 5V and 12V industrial logic. Its output options allow direct connection to microcontroller ADCs for analog readings or digital input pins for pulse counting, facilitating easy data acquisition with platforms like Arduino, PLCs, or Raspberry Pi.
