ATF80 Series
The ATF80 Series Smart Target Flowmeters utilize advanced target deflection technology, with precise target displacement measured by capacitance sensors. The digital signal processing provides a 4-20 mA output proportional to the volumetric flow rate, making it ideal for low-velocity and high-temperature gas and steam applications. Reconfiguration is simple by changing the target without replacing the entire meter. These flowmeters measure flow velocities as low as 0.1 m/s and handle high-temperature flare gas up to 450°C. Features include HART communication, low-pressure drop, and online calibration via Alia’s unique software. They are available in insertion or hot-tap types for large pipelines.
