Keywords of this article: Rosemount http://china-rosemount.cn/ The selection methods and criteria for Rosemount flowmeters of the same type also vary; each type of flowmeter has its own advantages and disadvantages. The appropriate type should be chosen based on the conditions under which it will be used. Different types of flowmeters require selection based on their respective performance characteristics and functions: 1. Electromagnetic flowmeters are suitable for measuring various corrosive liquids such as acids, alkalis, and salts; various flammable and explosive substances; as well as various industrial wastewaters, pulps, and slurries. Electromagnetic flowmeters cannot be used to measure gases, vapors, or liquids containing a large amount of gas. They are not suitable for measuring liquid media with very low conductivity, nor can they be used to measure fluids at high temperatures and pressures. 2. Selection of vortex flowmeters – Vortex flowmeters are primarily used for measuring the flow rate of fluids in industrial pipelines, including various media such as gases, liquids, and vapors. It is characterized by low pressure loss, a wide measurement range, and high precision; when measuring volumetric flow rate under operating conditions, it is hardly affected by parameters such as fluid density, pressure, temperature, and viscosity. ⒊ Selection of float flow meters (rotary flow meters): They can be used to measure the flow rate of liquids, gases, and steam, and are particularly suitable for measuring the flow rate of media with low flow velocities and small flow rates. ⒋ Selection of Coriolis mass flow meters: Mass flow meters are widely used in industries such as the petrochemical sector, and they represent one of the most advanced flow measurement devices available today. 5. Selection of thermal (gas) mass flow meters: These are suitable for measuring single gases as well as multi-component gases in fixed proportions. ⒍ At present in China, ultrasonic flowmeters can only be used to measure fluids below 200°C. Flow measurement challenges for highly corrosive, non-conductive, radioactive, and flammable/explosive media. ⒎ Selection of turbine flowmeters Turbine flowmeters are widely used for measuring various substances such as oil, organic liquids, inorganic liquids, liquefied gas, natural gas, gas, and low-temperature fluids.
