1. Analysis: What flowmeter is better for measuring oxygen?

Using a V-cone flowmeter for measuring oxygen is a good choice. The following is a detailed analysis: The principle and characteristics of V-cone flowmeter. V-cone flowmeter belongs to differential pressure flowmeter, and its core principle is to place a V-shaped cone in the pipeline to cause local contraction when the fluid flows through, thereby forming a pressure difference before and after the cone. The pressure difference is proportional to the square of the fluid velocity, and the flow rate can be calculated by measuring the differential pressure value. Its characteristics include: wide adaptability to media: suitable for almost all liquid and gas media, including industrial gases such as oxygen. Simple and reliable structure: no moving parts, high stability for long-term use, low maintenance cost. Accuracy and stability: The measurement accuracy is high and less affected by the flow field distribution, making it suitable for complex working conditions. Customized support: Selection and ordering can be made based on on-site requirements such as pipeline size, pressure rating, temperature range, etc. Figure: Installation diagram of V-cone flowmeter in pipeline. Special requirements for oxygen measurement and adaptability of V-cone flowmeter. Oxygen, as a strong oxidizing gas, needs to be focused on the following issues during the measurement process. V-cone flowmeter can effectively meet these requirements: degreasing treatment: Oxygen in contact with grease may cause combustion or explosion, so the flowmeter needs to undergo strict degreasing treatment. The material (such as stainless steel) and surface treatment process of V-cone flowmeter can

meet the requirements of degreasing and ensure safety. Pressure resistance and sealing: Oxygen is usually used in high-pressure environments, and V-cone flow meters can adopt high-pressure design and be equipped with reliable sealing structures to prevent leakage. Corrosion resistance: If oxygen contains trace amounts of moisture or impurities, corrosion-resistant materials (such as 316L stainless steel) should be selected. The material options for V-cone flow meters can cover such requirements. Compared with other flow meters, turbine flow meters have advantages: turbine flow meters measure flow by rotating the impeller, but impurities or particles in oxygen may cause the impeller to jam, affecting accuracy and lifespan; The V-cone flowmeter has no moving parts and is more suitable for gases containing impurities. Thermal mass flowmeter: Thermal flowmeters measure flow by exchanging heat between heating elements and fluids, but the high oxidation of oxygen may accelerate the loss of heating elements; The V-cone flowmeter has no direct contact heating components and a longer lifespan. Orifice flowmeter: Orifice flowmeter and V-cone flowmeter belong to differential pressure type, but the orifice plate is prone to wear, high pressure loss, and narrow range ratio; The conical structure of V-cone flowmeter reduces grinding vibration loss, lower pressure loss, and wider range ratio. Selection and use precautions degreasing treatment: Before installation, the flowmeter and pipeline should be thoroughly degreased to avoid residual grease and potential hazards. Material selection: Choose the appropriate material (such as 316L stainless steel or Hastelloy) based on oxygen purity, pressure, and temperature. Installation direction:
