ABSTRACT:
A measurement system includes a housing 10 with a duct 11 having an inlet 13 and outlet 14. Fluid passes though a number of apertures 47 in a chamber 21 and then through a measuring tube 40 which incorporates extensions 41. Fluid exits via chamber 22 and its apertures 47 to outlet 14. Transducers 36,37 are provided in chambers 53,50 and have an acoustic path through the measuring tube. Control electronics cause the transducers to send a burst of signals in alternate directions through the tube to determine fluid speed.
