ABSTRACT:
A plurality of transducers are positioned in the walls of a pipe conveying a fluid, the volumetric flow rate of which is to be measured. Opposed upstream and downstream transducers project acoustic energy toward one another through the fluid, along a plurality of parallel paths. Electronic circuitry coupled to the transducers provides an indication of the fluid velocity component along these paths and the values are modified by predetermined weighting factors. The transducers are placed in the pipe such that the acoustic paths are positioned at certain distances with respect to a reference.
