The Saier HZ21WA-C employs a precision turbine rotor to measure liquid flow. As fluid passes through the sensor body, it spins the turbine, generating a pulsed output signal proportional to the flow rate. This signal can be interpreted as either a frequency (digital) or a voltage (analog), providing compatibility with a wide range of data acquisition systems, from Arduino and Raspberry Pi to industrial PLCs.
Built for reliability in demanding environments, the sensor features a robust housing capable of withstanding pressures up to 1.75 MPa. Its electrical isolation, with an insulation resistance greater than 100 MΩ, ensures stable operation and protects connected electronics. The sensor is also suitable for monitoring compatible gases, extending its utility beyond liquid flow applications.
