Product Overview
The HFR Intelligent Roots Gas Flow Meter is a volumetric gas metering device that measures gas volume by counting the rotations of a pair of figure-eight rotors inside the measuring chamber. Featuring high measurement accuracy and excellent stability, it is suitable for commercial metering of medium- and high-pressure gases such as natural gas, coal gas, propane, and other gases. The meter is widely used in high-precision metering applications including urban gas transmission and distribution, petrochemical industries, and energy management systems.
Product Features & Advantages
- Ultra-High Accuracy: Provides extremely high measurement accuracy (±1% R) and excellent repeatability (≤0.2%), meeting commercial custody transfer requirements.
