How to Use Coriolis Mass Flowmeters. Coriolis mass flowmeters measure the mass flow of liquids, such as water, acids, caustic, chemicals, and gases/vapors. Because mass flow is measured, the measurement is not affected by fluid density changes. Be particularly careful when using Coriolis mass flowmeters to measure gas/vapor flows because flow rates tend to be low in the flow range (where accuracy is degraded).
For other uses, see Ophiuchus (disambiguation). Ophiuchus /ÉfiËjuËkÉs/ is a large constellation located around the celestial equator. Its name is from the Greek á½ÏÎ¹Î¿á¿¦ÏÎ¿Ï Ophioukhos; serpent-bearer, and it is commonly represented as a man grasping the snake that is represented by the constellation Serpens. Ophiuchus was one of the 48 constellations listed by the 2nd-century astronomer Ptolemy, and it remains one of the 88 modern constellations.
Big Bang Nucleosynthesis. The Universe's light-element abundance is another important criterion by which the Big Bang hypothesis is verified. It is now known that the elements observed in the Universe were created in either of two ways. Light elements (namely deuterium, helium, and lithium) were produced in the first few minutes of the Big Bang, while elements heavier than helium are thought to have their origins in the interiors of stars which formed much later in the history of the Universe.
