As the title asks: For Yokogawa vortex flowmeters with high accuracy, what is the measurement range within the instrument’s scale limit? Some experienced technicians say that the range of 10% to 90% of the full scale provides more accurate results. What do you all think? Thank you
Different diameters result in different measurement ranges, and the range within which accuracy is guaranteed varies depending on the measurement range. For example, the measurement range for DN15 is 0.3~6 M3/H, while the range within which accuracy is guaranteed is 0.94~6 M3/H; The measurement range for DN50 is 2.2~73 M3/H, and the range that ensures accuracy is 3.3~73 M3/H. You can take a look at the manual for details.
Choosing the most suitable instrument for the operating conditions is crucial, which is more important than discussing the accuracy of the instrument itself. There are many that claim 0.2 precision but are actually unusable.
The measurement accuracy of vortex street detectors is related to the Reynolds number and flow velocity; the selection criteria specify a flow velocity range within which accuracy is guaranteed, and it is not the overall measurement range that determines accuracy
Different calibers determine different measurement ranges, and the range that ensures accuracy varies depending on the measurement range
One-third to two-thirds is the most accurate
