Thermal anemometers low velocities: Frequency response and time-constant or cut-off frequency (NT VVS 089)

NT VVS 089

  • This method is to be used for the determination of the frequency response in the range 0.5 - 7 Hz of low velocity anemometers. The cut-off frequency or time constant is taken as a single measure of the frequency response.
