Precession vortex flowmeters are dedicated gas measuring instruments based on vortex precession theory. Integrated built-in Pt100 temperature and pressure sensors enable automatic real-time gas state compensation, outputting standard volume flow. Featuring no moving parts, IP65 protection and ExdIIBT4 explosion proof, they support pulse, 4-20mA and RS485 signals for natural gas and industrial gas trade metering.
Specially designed built-in vortex stabilizer forms regular swirling airflow efficiently, effectively restraining turbulent flow interference. Even with medium pressure loss during operation, the internal fixed structural component maintains complete vortex precession, preventing signal distortion under unstable gas supply conditions.
Standard Exd explosion-proof design meets hazardous gas area requirements, with local LCD display and multi-signal remote output functions. The circuit module features low power consumption and stable signal acquisition, reducing frequent on-site inspections for factory and municipal gas trade metering projects.
Integrated Pt100 temperature and pressure transmitters automatically compensate gas volume for varying pressure and temperature. Equipped with anti-vibration signal filtering circuits, it resists pipeline vibration interference. It delivers steady standard volumetric flow data in outdoor, humid and fluctuating industrial environments.
