Study on Adaptability of Single Acoustic Path Altrasonic Flowmeter in Single Bending Pipe Flow Field

Based on influence of non-perfect flow field to altrasonic flow measurement,measuring errors of Both direct and refiactive single acoustic path arrangements were studied in single Bending pipe flow field.Through thearetical analysis of error,error-angle relation curve in different acoustic path arrangements and installation angles were ealculated.Then,it is concluded that there always is an instalated angle in that the measuring error is zero theore tically for each installation mode.Therefore,for low accuracy requirement,direct radial arrangement is adopted,But rational acoustic path installation angle should Be selected;for high accaracy requirement,refractive arrangement is Better.
