ABSTRACT:
Various embodiments of the present invention provide a flow meter device having a laser Doppler anemometer (LDA) which measures the instantaneous center line velocity of fluid flow in a pipe. The flow meter may process the instantaneous velocity so obtained to compute the volumetric flow rate, mass rate, and/or other flow characteristics (e.g., as instantaneous quantities and/or integrated over a time interval) The flow meter may use an electronic processing method. The electronic processing method may provide essentially an exact solution to the Navier-Stokes equations for any periodically oscillating flow.
