When gas flow encounters changes in pipe size, direction, or other disturbances, the flow profile becomes disrupted, compromising measurement accuracy.Flow conditioningbecomes essential when a limited straight run prevents achieving a developed profile naturally. Flow conditioners create a known, repeatable ...
Figure 49.Flowrate/pipe-size relation – magnetic flowmeter A Kent ‘Veriflux’ flowmeter system comprising a sensing unit (the detector head), a transmitting unit and receiving instruments as required is shown schematically inFigure 50. The duties of the transmitting unit may be broadly defined ...

Increment size is an important decision. It is obvious that the mass flow rate at the end of an increment will be less than the mass flow rate at the beginning, but this analysis ignores that (hopefully slight) change. The longer we apply an overstated flow rate, the worse the analysis ...

the flow of a fluid traveling at an average velocity of a 1 meter per second through a pipe with a 1 square meter cross-sectional area is 1 cubic meter per second. Note that Q is a volume per unit time, so Q is commonly denoted as the “volumetric” flow rate. Now consider the fo...
