Anemometers measure speed; pneumatic probes measure pressure and direction. Together, they paint a full picture of flow fields—but only if you sync them right. Mismatched data can lead to wrong conclusions (e.g., thinking a flow is “fast” when it’s actually “high-pressure but slow”). Here’s how to combine them effectively.

Setup best practices:

· Positioning: Place the anemometer 2–3x its diameter away from the probe to avoid turbulence interference. For example, a 10mm anemometer needs 20–30mm clearance from a 5mm probe.

· Height alignment: Ensure both measure at the same flow layer (e.g., 5cm from the tunnel wall). Vertical misalignment causes speed/pressure mismatches.

Synchronization steps:

1. Connect both to the same data logger or trigger source (e.g., a 1kHz clock pulse).

2. Set identical sampling rates (e.g., 100 Hz) to avoid time gaps in data.

3. Post-test, overlay their timestamps to link speed spikes with pressure changes (e.g., “At 12:05:30, speed hit 30 m/s and pressure rose to 1.2 bar”).

Scenario-specific tips:

· Turbulent flows: Use a hot-wire anemometer (fast response) with a 5-hole probe to capture rapid fluctuations.

· Low-speed flows (≤10 m/s): A cup anemometer + 3-hole probe works—no need for expensive gear.

· High-temperature flows: Pair a laser Doppler anemometer (non-contact) with a heat-resistant probe (Inconel tip) to avoid melting.

Data validation trick:
In steady flow, pressure (from the probe) and speed (from the anemometer) should correlate via Bernoulli’s equation. If they don’t, check for sensor drift or positioning errors.
