1. Core Measurement Advantages

• High measurement accuracy: Typical accuracy ranges from ±1.0% to ±1.5% FS (±0.5% FS for high-precision models), with repeatability error ≤0.3%, meeting the requirements of trade settlement and process control.
• Wide turndown ratio: Standard ratio is 1:10 to 1:20, expandable to 1:30 for certain models, covering wide flow range measurements (e.g., steam flow from low to full load).
• Broad medium adaptability: Capable of measuring three types of media—gases (natural gas, nitrogen, compressed air, etc.), liquids (water, oils, chemical solvents, etc.), and steam (saturated/superheated steam)—without replacing core components for different media.

2. Structural & Installation Features

• No moving parts: The core measurement unit has no mechanical rotating or wearable components, resulting in low failure rate and long service life (5~10 years under normal conditions) with minimal maintenance costs.
• Low pressure loss: Resistance to fluid flow is only 1/3~1/5 of orifice flowmeters, reducing pipeline energy loss, especially suitable for large-diameter and low-pressure applications.
• Easy installation: Supports horizontal, vertical, and inclined mounting, with relatively loose straight pipe requirements (typically 10D upstream / 5D downstream; some models with rectifier structure can be shortened to 5D upstream / 3D downstream, where D = pipe diameter), ensuring strong on-site adaptability.
• Compact structure: Small size and light weight, ideal for space-constrained environments (e.g., narrow equipment rooms, high-altitude pipelines).

3. Working Condition Adaptability

• High temperature & pressure resistance: Standard models withstand -40℃~350℃ and ≤4.0MPa; custom models can extend to 500℃ and 16MPa, suitable for measuring steam and high-temperature process fluids.
• Strong anti-interference capability: Equipped with piezoelectric or capacitive sensors combined with digital filtering technology, effectively resisting pipeline vibration, electromagnetic interference, and medium pulsation (some models feature anti-vibration design, with vibration-induced error ≤±0.1% FS).
• Corrosion/wear resistance options: For special media (acid-base solutions, dusty gases), materials like stainless steel, PTFE lining, and Hastelloy are available to expand application scenarios.

4. Operational & Maintenance Advantages

• No on-site calibration required: Based on physical measurement principles, factory calibration with standard devices eliminates the need for re-calibration on-site (provided medium parameters match calibration conditions).
• Rich output signals: Supports 4~20mA analog signal, pulse signal, and RS485 (Modbus protocol) digital signal output, directly connecting to PLC, DCS systems, or data acquisition equipment for automated control.
• Low operational cost: No consumables or regular disassembly required; only periodic checks of flange tightness and sensor wiring are needed, minimizing maintenance workload.

5. Limitations (for selection reference)

• Insensitive to low-velocity, high-viscosity media: Requires Reynolds number Re ≥20,000 (gases) or ≥5,000 (liquids); otherwise, measurement error increases. Not suitable for heavy oil, viscous liquids, etc.
• Medium cleanliness requirement: Large solid particles (particle size ＞5mm) may clog sensors or damage detection elements, requiring filters for use.
• Inapplicable to non-Newtonian fluids: Slurries or fluids with high suspended solids will affect vortex stability, leading to measurement failure.
