Vortex nitrogen flow meter adopts Karman vortex principle, optional integrated T&P compensation, directly outputs standard nitrogen volume. Stainless steel wetted parts with ExdII CT6 explosion-proof, ideal for industrial nitrogen pipeline continuous measurement.
Suitable for pure nitrogen, mixed nitrogen and inert gas flow measurement
Optional built-in temperature & pressure auto compensation for standard flow output
Full SS304/316L flow body, corrosion-resistant to dry nitrogen
No moving internal parts, low pressure loss, long service life
Wide turndown ratio up to 15:1, stable low-flow detection
Multi signals: pulse, 4-20mA, isolated RS485 Modbus / HART
ExdII CT6 explosion-proof & IP65 protection for nitrogen workshops
LCD display for instantaneous & cumulative standard nitrogen flow
Flange/clamp/thread multi connection, DN15~DN300 full calibers
