Abstract
In order to improve precision of ultrasonic wave flow measurement
factors which affect measurement precision are analyzed
and measurement error caused by temperature
current speed and built-in reflector plate is analyzed
and the concrete error compensation method is proposed. Experiment shows that it is valid to reduce measurement error and improve measurement precision after the error caused by above influencing factors are compensated and revised.
