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. 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).
Radium is a silvery-white metal. It is highly radioactive and its decay product, radon gas, is also radioactive. One result of radiumâs intense radioactivity is that the metal and its compounds glow in the dark. When it is exposed to air, it reacts with nitrogen to quickly form a black coating of radium nitride.iscovery of Radium. Radium was discovered in 1898 in Paris, by Marie S. Curie and her husband Pierre in pitchblende (mainly uranium dioxide, UO 2).
