SF-98-20-5 -- Requirements and Guidelines for Low-Velocity Measurements

In this paper, new requirements for the characteristics of anemometers used for low-velocity measurements indoors, as well as requirements for the signal processing, are presented. The static calibration, dynamic response, and temperature compensation of the anemometers, as well as the directional sensitivity and the design of the velocity transducer, are considered, together with the period and the sampling rate of the measurements. The requirements in ASHRAE Standard 55 (1992), ASHRAE Standard 113 (1990), and ISO Standard 7726 (1985) are modified, and new requirements not considered in the current standards are developed and suggested for inclusion in future standards.
