This vortex gas flow meter works on the Karman vortexprinciple, fitted with integrated temperature and pressuresensors for automatic gas compensation. Constructedfrom stainless steel with no moving parts, it delivers stablevolume flow readings and suits nitrogen, compressed airand industrial fuel gas pipeline measurement.
Built-in temperature and pressure auto-compensation module to output accurate standard gas volume.
Full stainless steel wetted parts, high temperature and pressure resistance for various industrial gases.
No internal movable parts, low abrasion and long service life with little maintenance.
Wide measuring range ratio, covers low to high gas flow working conditions.
Multiple signal outputs: 4-20mA, pulse and RS485 for automated control systems.
Standard flange/clamp/thread connections, easy installation for DN15~DN300 pipelines.
