Buying Guide: Pitot Tubes For Air Flow Measurement
- Material and durability: Stainless steel (304) tubes resist corrosion and dust, making them suitable for HVAC and industrial environments.
- Geometry: S-type versus L-type affects how flow is sampled. S-types are common for bi-directional flow, while L-types offer direct static/dynamic pressure access in some arrangements.
- Diameter and length: Larger diameters and longer probes reach deeper into ducts but may add rigidity and weight. Ensure compatibility with your ports and testing rig.
- Static vs dynamic measurement: Some models measure static and total (dynamic) pressure, while others are bi-directional or specialized for air speed in RC or lab contexts. Choose based on your required data set.
- Connection and compatibility: Consider how the pitot tube interfaces with your gauges, data loggers, or flight controllers. Scale and thread sizes matter for secure connections.
- Maintenance: Look for corrosion resistance and ease of cleaning, especially in dusty or moist environments. Stainless steel tubes generally offer longer service life.
- Application scope: HVAC duct testing, calibration labs, irrigation systems, and RC model testing each have distinct requirements. A tube with balanced static/dynamic capabilities suits versatile use, while specialized models can optimize for specific tasks.
