WebMeasurements are performed by measuring the velocity of suspended particles in a remote sampling volume (point of the three converging acoustic beams) based on the Doppler shift effect [32,33,34]. The sampling volume is located either 5 or 10 cm from the tip of the probe; some studies show that the distance may vary slightly [ 35 ], while the ... WebThe hot wire anemometer is best for accurately measuring air flow at very low velocities (eg., under 2000 ft/min). Some models are designed to measure velocities as high as 15,000 ft/min but still have very accurate measuring capability down to much lower speeds. The vane anemometer relies in a rotating impeller to sense air velocity.
