Lower plane Lower plane Measure the velocity at any point or over any zone in the flow-field 1 6.277 500 The velocity at each point in time 0.9 0.8 400 within each zone is calculated by correlating the instantaneous 0.7 300 concentration of one plane with the same zone in the other plane...
As the velocity is calculated in each zone across the flow cross-section, the measurement does not suffer from the gross errors exhibited by other measurement systems which rely on calculating an average velocity figure over the pipe cross-section. Most alternative measurement technique either require...
