Vortex Flow Meter – Reliable Steam, Gas & Liquid Flow Measurement for Industrial Applications
Product Description
The Vortex Flow Meter is a robust, high-precision digital flow measurement device designed for reliable monitoring of steam, gases, and liquids in industrial process applications. Based on the von Kármán vortex shedding principle, it detects flow velocity by measuring pressure pulses generated by alternating vortices behind a bluff body, ensuring stable and accurate readings without moving parts.
Unlike traditional turbine or differential pressure meters, this flow meter offers exceptional durability, low maintenance, and high turndown ratios (up to 30:1), making it ideal for variable flow conditions in power plants, chemical processing, and HVAC systems. Its advanced digital signal processing and temperature compensation deliver consistent performance across wide temperature and pressure ranges.
With multiple output options and compact design, the Vortex Flow Meter seamlessly integrates into existing SCADA/PLC systems, helping users reduce energy costs, improve process efficiency, and minimize downtime from mechanical wear.
