1 Answer. There are two basic configurations of coriolis flow meter: the curved tube flow meter and the straight tube flow meter. Reference : Mass flow meter. Chemtrols is a leading manufacturer of coriolis flow meter in India that supplies various process analytics products to commercial industries in India.
Radium is a chemical element with symbol Ra and atomic number 88. It is the sixth element in group 2 of the periodic table, also known as the alkaline earth metals.Pure radium is almost colorless, but it readily combines with nitrogen (rather than oxygen) on exposure to air, forming a black surface layer of radium nitride (Ra 3 N 2).t is the sixth element in group 2 of the periodic table, also known as the alkaline earth metals.

Some radioactive elements glow because of their radioactive decays. They emit electrons or alpha particles, changing from one kind of element to another, and as the electrons in the atoms rearrange themselves to the new atom's configuration, they emit light. Radium was used for watch dials because it glows green.articulrly nasty radioactive elements include radon and radioactive iodine. Radon is a chemically inert gas with a short half-life (and therefore decays rapidly, emitting radiation faster than other elements).
