This accelerated flow drives the turbine impeller to rotate, with the rotational speed being proportional to the flow rate. As the impeller rotates, the magnetic sensor synchronously generates pulse signals. The electronic head performs real-time compensated measurement by integrating these pulse signals with temperature and pressure data, achieving integrated synchronous metering.Complies with ISO 9951 technical requirements; features 3DN meter body length and passes high/low-level disturbance tests.Measures gas temperature, pressure, and flow rate with automatic flow tracking compensation and compressibility factor correction; displays accumulated gas volume at base conditions.Wide flow range, high repeatability, superior accuracy, minimal pressure loss, and low start-up flow.Incorporates five-segment meter factor configuration with automatic correction.Utilizes dedicated integrated flow conditioner with anti-strong magnetic interference protection.Minimal straight-pipe requirements (≥2DN upstream, no requirement downstream).Integrated pressure/temperature sensors ensure high safety, compact structure, and aesthetic design.Self-diagnoses sensor faults and displays error codes directly on the screen.Single lithium battery operates >5 years with under-voltage alarm, optimized for IC card management system integration.Intelligent flow computer rotates 350° for optimal viewing angle, enabling direct reading in any installation orientation.Integrated real-time clock and non-volatile memory prevent data loss under all conditions (including power failure).RS-485 communication interface with advanced data management software supports automatic report generation and printing.Certified explosion-proof (Exia IIC T4) and weather-resistant (IP65) construction.Company ProfileCertifications
