Are their measurement principles the same?
The measurement principle is the same; there is a slight difference in construction.
What was said on the 3rd floor is right! The measurement principle for both is the same; other pressure gauges of this type include Weitiba and Delta Ba. Anubaa has a relatively larger differential pressure, which makes it more suitable for measurement; it is part of the Emerson portfolio and its price is also relatively high. DeltaBar can measure two-way flow.
The measurement principle is the same; it involves an average velocity tube, with the differential pressure being measured using a manometer. The hardware structure differs slightly, resulting in a different appearance
There is also ABB’s TORBAR auger; the principle is the same, it’s just that the cross-sectional view of the probe differs – for ABB’s product it’s T-shaped, while for Weiliba it’s bullet-shaped
The measurement principle is the same; it’s just that the structure differs, as do the applications and the media being measured.
For ballets, we have used brands like Weiliba in China, A Liu from Luomeng, Tuoba, and Deba. Overall, it seems that imported products are superior: the theoretical flow rates calculated based on the instrument readings match more accurately, while those of domestic products do not. There’s really a lot to know about this category.
