AVF7000 Series

Datasheet

The AVF7000 Series Vortex Flowmeter utilizes the Von Karman theory of vortices generated by a bluff body, with vortex frequency directly proportional to the volumetric flow rate. Ideal for gases, steam, and liquid applications, the flowmeter features no moving parts and offers flange or wafer connections. It provides local flowrate and total flow indication, along with 4-20 mA HART and pulse outputs. Its microprocessor design filters out erroneous signals and vibration interference, ensuring reliable performance. Key features include automatic temperature and pressure compensation, simplified setup, self-diagnostics, a wide selection of sizes, operation up to 420 °C, and non-volatile memory for settings and calibration. The AVF7000 delivers versatility and precision across demanding flow measurement applications.
