抄録

In the field of measurement, we often encounter the need to measure pipe lengths indirectly. We have developed an on-line pipe length measurement system with one acoustic sensor from the viewpoints of ease to be used in various applications and its cost. The system made use of the stationary wave generated by hitting the pipes or the one spontaneously generated in the pipes. The system realized a highly accurate measurement by modeling the stationary wave as state variables of a linear dynamic system and applying Kalman filters and maximum likelihood method.<br>The paper discusses the optimal location of the acoustic sensor to realize a much higher accurate pipe length measurement. Experiments will show the validity of the optimal sensor location.
