Supmea LUGB-SUP Vortex Flowmeter
Product Overview
The Supmea LUGB-SUP Vortex Flowmeter is a robust and accurate device designed for measuring the flow rate of steam, gases, and low-viscosity liquids in industrial pipelines. Based on the Karman vortex principle, it generates vortices behind a bluff body, detecting flow velocity through pressure fluctuations captured by a piezoelectric crystal. Available in standard, temperature/pressure compensated, and anti-vibration models, the LUGB-SUP ensures reliable performance with no moving parts, minimal maintenance, and high durability. With options for pulse, 4-20 mA, and RS485 outputs, it integrates seamlessly into control systems, making it a cost-effective choice for petroleum, chemical, metallurgy, and environmental protection industries.
