Title: Method and device for measuring partial speed in moving fluid containing solid particle
Inventor: TAKEDA YASUSHI
IPC: G01P5/24
Filed: 1986-05-09
Abstract: A measure window (29-30, FIG. 2d) is provided in a Doppler velocity profile (FIG. 2c) by deleting an initial section (T1) and a terminal section (T2) of each emission cycle of a train of ultrasound of a period T so as to conserve only the section (To) which it is desirable to study. The conserved section (To) is thereafter segmented into a certain number (N) of measure channels. The advantage of restricting the zone divided into channels to the part which is really useful is that the definition of the profile which is obtained is improved, even when the emitter-receptor of ultrasound is located at a relatively important distance in comparison with the depth of the zone which is studied.
