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).
History and Uses: Radium was discovered by Marie Sklodowska Curie, a Polish chemist, and Pierre Curie, a French chemist, in 1898. Marie Curie obtained radium from pitchblende, a material that contains uranium, after noticing that unrefined pitchblende was more radioactive than the uranium that was separated from it.adium's most stable isotope, radium-226, has a half-life of about 1600 years. It decays into radon -222 through alpha decay or into lead -212 by ejecting a carbon -14 nucleus. The Curie, a unit used to describe the activity of a radioactive substance, is based on radium-226.
