The VSE Flow Meter VS10.04 Series is a positive displacement flow meter that combines high-precision measurement with explosion-proof performance, developed and manufactured by the German company VSE. Utilizing an advanced gear measurement principle, this series enables accurate flow measurement of liquid media while offering exceptional explosion-proof characteristics, making it suitable for industrial environments with potential explosion risks. Its core design features include a compact structure, high reliability, a wide range ratio, and excellent medium compatibility, meeting the stringent flow measurement requirements of various industrial applications. High-Precision Function Analysis: The VS10.04 Series flow meter operates on the positive displacement measurement principle, where a pair of meshing gears rotate within the measurement chamber, dividing the liquid into fixed-volume segments and calculating flow rate by counting the number of gear rotations. This measurement method is unaffected by changes in fluid properties such as viscosity and density, ensuring measurement accuracy across various operating conditions with the following specifications: Basic error: ±0.1% (within measurement range); Reproducibility: ≤0.05%; Resolution: 0.001 L/min; Linearity:优于 ±0.1%. These precision metrics enable the VS10.04 series to excel in applications requiring high measurement accuracy, such as precision metrology and process control.  **Factors Affecting Precision and Optimization Measures**: Although the flow meters in this series inherently possess high precision, the following factors require attention in practical applications: 1. **Installation**: Ensure sufficient straight pipe sections before and after the flow meter to minimize fluid disturbance affecting measurement accuracy. 2. **Media Temperature**: Temperature fluctuations may cause thermal expansion and contraction of internal components, impacting measurement chamber volume. The VS10.04 series employs temperature compensation technology to maintain high precision across a temperature range of-40°C to +120°C. 3. **Pressure Fluctuations**: Excessive pressure variations may compromise the rotational stability of gears. It is recommended to install pressure stabilization devices in fluid systems to minimize the impact of pressure fluctuations on measurement accuracy. Explosion-proof Function Range: The VS10.04 series flow meters have obtained multiple international explosion-proof certifications: ATEX certification: Complies with European explosion-proof standards, suitable for potentially explosive environments; IECEx certification: Explosion-proof certification from the International Electrotechnical Commission, applicable worldwide in explosion-proof zones; UL certification: Certified by the Insurance Institute for Technology (US), meeting North American explosion-proof requirements. Explosion Protection Ratings: The series meets Ex II 2G/Ex d IIC/T6 Gb standards: -Ex II: Suitable for explosive gas environments other than coal mines; -2G: Zone classification applicable to Zone 1 (environments where explosive gas mixtures may form during normal operation) and Zone 2 (environments where explosive mixtures are unlikely or transient); -Ex d: Explosion-proof design that isolates internal gas mixtures from the external environment, preventing explosion propagation; -IIC: Applicable to the most hazardous gases such as hydrogen and acetylene; -T6: Temperature rating ensuring maximum surface temperature does not exceed 85°C, suitable for low-ignition-point explosive gas environments. Explosion-Proof Structural Design: The VS10.04 series features a robust explosion-proof structure constructed from high-strength aluminum alloy, offering excellent pressure and impact resistance to withstand internal explosion pressures without rupture. The cable introduction device simultaneously prevents flames and high-temperature gases from escaping through shell gaps and igniting external explosive gases. It employs explosion-proof gland connections to ensure airtight sealing between the cable and the casing, preventing explosive gases from entering the equipment through cable entry ports. Internal components comply with explosion-proof standards, including explosion-proof sensors and terminals, to avoid spark generation or excessive heat during normal operation or faults. Application scenario analysis: The petrochemical industry involves extensive handling of flammable and explosive liquid media during production processes, such as crude oil, gasoline, diesel, and chemical raw materials. The VS10.04 series flow meters, renowned for their high precision and explosion-proof capabilities, serve as ideal flow measurement devices for the following applications: 1. Raw material dosing: Precise measurement of various chemical feedstocks entering reactors ensures accurate reaction ratios and enhances product quality. 2.成品 filling: Real-time flow monitoring during petroleum product filling controls filling volumes, preventing spills that could pose safety risks or cause waste. 3. Pipeline transportation: Flow measurement of flammable and explosive liquids in pipelines provides data support for production scheduling and process control. The pharmaceutical industry demands high accuracy in material dosing, particularly since solvents and other media used in certain processes are flammable and explosive. The VS10.04 series enables precise measurement of component additions during drug formulation, ensuring consistent product quality and solvent recovery through flow monitoring for efficient resource utilization and cost control. In the coatings and ink industry, where solvents and resins are often flammable and explosive materials requiring precise ratio control, these flow meters ensure accurate mixing ratios and improved product performance. Real-time flow monitoring during production allows timely parameter adjustments to maintain continuity and stability. In automotive manufacturing, coating processes involve extensive use of paints and solvents, making these flow meters particularly critical. These media possess flammable and explosive properties. The VS10.04 series flow meter is designed for precise measurement of paint flow rates in coating systems, enabling accurate control of coating thickness, quality, and solvent ratios while ensuring optimal solvent dosage and meeting paint viscosity requirements. With its high-precision measurement capabilities and comprehensive explosion-proof features, the VS10.04 series flow meter finds extensive applications in industrial sectors with potential explosion risks—including petrochemicals, pharmaceuticals, coatings/ink manufacturing, and automotive production. Its advanced measurement principles, exceptional accuracy, and robust explosion-proof design meet stringent flow measurement demands across industries, providing robust safeguards for safe, stable, and efficient industrial operations. In practical applications, users should select and install the flow meter appropriately based on specific operational conditions to maximize its performance advantages.
