Coriolis Mass flow meter, also known as Coriolis mass flow meter, is a flow measuring instrument that adopts a new measurement principle. It has developed rapidly since it entered commercialization in the early 1980s.
Coriolis mass flowmeters can be used in petrochemical, chemical, pharmaceutical, paper, food, and energy industries. They have been widely used in the detection and control of process and custody transfer measurement and other occasions. Highly valued by the measurement industry and welcomed by the majority of users, it is a new type of mass flowmeter that is more advanced and has a rapid development trend in the world today.
Compared with traditional flow measurement methods, Coriolis mass flowmeters have the following outstanding features:
(1) It can directly measure the mass flow of the fluid in the pipeline, that is, directly obtain the mass flow signal. This measurement method does not require the measurement and conversion of intermediate parameters, thereby avoiding the errors introduced by multiple intermediate links. The measurement accuracy of mass flow is high, and the repeatability is good, and it can be in a relatively large range ratio range. , To achieve high-accuracy direct measurement of fluid mass flow.
(2) The applicable fluid medium is wide. In addition to measuring uniform fluids with general viscosity, it can also measure various high-viscosity, non-Newtonian fluids. For fluids containing a small number of solid-phase components and fluids containing a small number of gas-phase components, it can also be applied under certain conditions.
In principle, the measurement accuracy of the Coriolis mass flowmeter can be approximately considered not to be affected by the physical parameters of the measured medium and the flow state in the tube.
(3) There are no obstacles and moving parts inside the flowmeter pipe through which the fluid flows, so the reliability is high, the service life is long, and the amount of daily maintenance is small.
(4) In addition to directly measuring the mass flow of the fluid, it can also directly measure the density and temperature of the fluid. The intelligent flow transmitter can provide a variety of parameter display and control functions. The function is an integrated flow measurement and control instrument.
