The Saier HZ21TA 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 series of pulses or an analog voltage proportional to the flow rate. This robust sensing principle ensures reliable performance across a broad measurement range.
Engineered for system integration, the sensor features a wide input voltage tolerance and low power consumption, making it compatible with 5V and 12V logic systems common in industrial automation, IoT nodes, and DIY electronics. Its housing is built to withstand working pressures up to 1.75 MPa, offering durability for continuous monitoring applications in various environments.
