1. Sharing: Using V-cone flow to measure carbon dioxide

It is feasible to use V-cone flowmeter to measure carbon dioxide. The following is a specific analysis: The core feature of V-cone flowmeter is that it is a new type of differential pressure flow instrument. Its working principle is based on the differential pressure signal generated when the fluid flows through the conical throttling device, and the operating flow rate is calculated by measuring the differential pressure. Its core advantages include high signal stability: the conical structure makes fluid flow more stable, reduces turbulence interference, and has small fluctuations in differential pressure signals. Wide range ratio: can adapt to large-scale flow changes, suitable for scenarios with large flow fluctuations. Long service life: no moving parts, strong wear resistance, low maintenance cost. Strong adaptability: can be matched with different media, temperature, and pressure conditions through selection. Figure: Schematic diagram of the working principle of V-cone flowmeter. Physical properties and measurement requirements of carbon dioxide. Carbon dioxide (CO?) is a colorless, slightly acidic gas commonly used in industrial emissions, biological reactions, gas storage, and other scenarios. The measurement should pay attention to the following characteristics: density and compressibility: CO? Density varies significantly with pressure and temperature, and the flowmeter needs to be calibrated under operating conditions. Corrosivity: Dry CO? Non corrosive, but may form carbonic acid when containing moisture, so corrosion-resistant materials (such as 316L stainless steel) should be selected. Measurement range: In industrial processes, the CO flow

rate may vary greatly (such as from a few cubic meters/hour to thousands of cubic meters/hour), requiring a wide flow measurement range. Compatibility of differential pressure measurement principle for measuring CO with V-cone flowmeter. V-cone flowmeter calculates flow rate through differential pressure, without being limited by gas type, and only requires correction factors based on parameters such as CO density and viscosity. For gases with significant density changes such as CO, it is necessary to input actual operating parameters (such as pressure and temperature) into the fiber selection process to ensure the accuracy of the calculation model. The matching of range ratio and flow rate fluctuations: During CO emissions or treatment processes, the flow rate may fluctuate significantly due to process adjustments. The range ratio of V-cone flowmeter can usually reach 10:1 or more, covering various scenarios from low flow leakage detection to high flow transmission. If CO? Contains moisture or impurities, corrosion-resistant materials such as 316L stainless steel and Hastelloy should be selected to avoid measurement deviation caused by corrosion of the throttling device after long-term use. Dry CO? Ordinary stainless steel can be used in the scenario to reduce costs. Installation and maintenance advantages: The V-cone flowmeter has a simple structure, no moving parts, and is suitable for high temperature, high pressure, or vibration environments (such as CO? Compression storage scenarios). The straight pipe section is required to be relatively short (usually 5D in the front and 3D in the back), making it easy to install on site. Selection and usage precautions: Calibration of operating parameters: Input actual pressure
