Abstract
A measurement device, including a doppler LiDAR unit that includes an optical transmitter operable to transmit a signal, and which further includes an optical receiver operable to receive a backscatter signal that includes a portion of the signal, and the measurement device also includes a processor operable to determine a doppler shift as between the signal and the backscatter signal, and use the doppler shift to determine a volumetric flow rate of a fluid to which the signal is directed, and from which the backscatter signal is received.
