Product Description
AFD4 Series Vortex Liquid Flow Meter
Product Overview
The AFD4 series is a vortex liquid flow meter based on the Von Karman vortex principle, designed for accurate and reliable flow measurement. It features excellent repeatability, high precision, low pressure loss, and resistance to contamination due to its no-moving-parts design. The sensor measures the frequency of vortices shed by a bluff body to calculate the fluid flow rate. Its long lifespan, fast response, and drift-free operation make it an ideal choice for cost-sensitive OEM applications in demanding industrial environments, energy metering, environmental protection, laboratories, and transportation.
