The invention discloses a horizontal zero calibration method for an instrument mounting platform of a flow velocity detection vehicle. The horizontal zero calibration method comprises the following steps: 1, fastening and mounting the instrument mounting platform on a detection vehicle mounting frame through bolts; 2, enabling the detection vehicle to conduct linear motion displacement adjustment on the guide rails through pulleys; 3, mounting the range finder at the central axis position of the instrument mounting platform, and adjusting the orientation of the range finder; 4, pushing the instrument mounting platform to rotate by 90 degrees on the mounting frame; 5, measuring the distance between the central axis of the instrument mounting platform and the guide rail along the guide rail; and 6, further adjusting the position of the instrument mounting platform according to the measured distance. According to the method for calibrating the horizontal zero position of the instrument mounting platform of the f
