Anemometer attachment

Anemometer Funnel Adapter – Airflow Concentrator for Improved Measurements

This 3D-printed adapter is designed as a funnel attachment for an anemometer, helping to capture and direct airflow more effectively toward the sensor. It is especially useful for measuring low air velocities, such as in heat recovery ventilation (HRV), HVAC systems, or air ducts.

🔧 Key Features:

• Improves anemometer sensitivity at low airflow speeds
• Helps stabilize and direct the airflow
• Ideal for measuring air outlets (e.g. ventilation systems)
• Easy to install – fits onto standard anemometer probes
• Durable design suitable for repeated use

📐 Description:

The funnel shape concentrates the airflow into a smaller cross-section, increasing the air velocity at the measurement point. This allows the anemometer to detect even very weak airflow more reliably.

🖨️ Printing Recommendations:

Material: PLA / PETG

Layer height: 0.2 mm

Infill: 10–20%

⚠️ Note:

This adapter may affect absolute measurement values (it increases airflow speed at the sensor). It is best used for comparative or relative measurements, or after proper calibration.
