1.Introduction
Hoffer's HFCM mass flowmeter, known as Coriolis mass flowmeter, is a flow meter using the principle of Coriolis force, can be used in petroleum, petrochemical, natural gas, chemical, cryogenic, pharmaceutical, paper, food and energy industries. In the process of detection and trade handover measurement occasions, has been widely used, has been highly valued by the international flow measurement session and the majority of users welcome, is the world's more advanced, fast development trend of a new flow measurement instrument.
Compared with the traditional flow measurement method, the Coriolis force mass flowmeter has obvious advantages: 1) the Coriolis force mass flowmeter can directly measure the mass flow of the fluid in the pipeline, without the conversion of the intermediate parameters, so as to avoid the measurement error caused by the intermediate link. 2) It has high accuracy and good repeatability in mass flow measurement. It can directly measure the mass flow of the fluid with high accuracy within a relatively large range ratio. 3) Coriolis force mass flowmeter can measure a wide range of fluid, in addition to the general viscosity of gas and liquid can be measured, but also can measure a variety of high viscosity, non-Newtonian fluid. It can also be used under certain conditions for slurry containing solid phase components and fluid containing trace gas phase components. 4) The vibration amplitude of the measuring pipe of the Coriolis force mass flowmeter is small, and it can be regarded as an inactive part. There are no obstructing parts and moving parts inside the flowmeter pipe through which the fluid flows, so it has high reliability, long service life and small daily maintenance. 5) the coriolis force mass flowmeter, besides can directly measure the quality of the fluid flow but also can directly measure the fluid density and temperature, but also by the mass flow rate and fluid density derived bicomponent solute concentration in the solution, can provide a variety of parameter display and output, is a kind of integrating multifunction flow measurement and control instrument.
