The Saier HZ21WI Water Flow Sensor employs a reliable turbine mechanism to translate fluid velocity into a measurable electrical signal. As liquid flows through the sensor body, it spins an internal impeller, generating a pulse frequency or analog voltage proportional to the flow rate. This principle ensures consistent and repeatable measurements suitable for monitoring and control applications.
Built for durability, the sensor features a robust housing capable of withstanding pressures up to 1.75 MPa, making it suitable for various plumbing and industrial fluid systems. Its wide 4.5-18V DC input range allows compatibility with 5V and 12V logic systems common in Arduino, Raspberry Pi, and industrial PLC environments. The sensor outputs a clean signal with high-level voltage ≥4.5V and low-level ≤0.5V, ensuring reliable digital interfacing.
