Description

Technical Field

[0001] The invention relates to the technical field of mass flowmeters, in particular to a novel suspension structure of a mass flowmeter. Background Art

[0002] The volume of a fluid is a function of the temperature and pressure of the fluid and is a dependent variable, while the mass of a fluid is a quantity that does not change with time, space temperature, and pressure. As mentioned above, the flow measurement value of commonly used flow meters, such as orifice flowmeters, laminar mass flowmeters, turbine flowmeters, vortex flowmeters, electromagnetic flowmeters, rotor flowmeters, ultrasonic flowmeters, and elliptical gear flowmeters, is the volume flow rate of the fluid. The amount of fluid involved in scientific research, production process control, quality management, economic accounting, and trade transfer is generally mass. Using the above flowmeter to measure only the volume flow of the fluid often cannot meet people's requirements, and it is usually necessary to try to obtain the mass flow of the fluid. In the past, the mass of the fluid could only be obtained indirectly through correction, conversion, and compensation after measuring parameters such as the temperature, pressure, density, and volume of the fluid. This measurement method has many intermediate links, and the accuracy of mass flow measurement is difficult to guarantee and improve. With the development of modern science and technology, some metering methods and devices for directly measuring mass flow have emerged one after another, thus promoting the progress of flow measurement technology.

[0003] At present, the vibration tube of the straight tube mass flowmeter is welded to the shell and the body. The characteristics of this method are: the structure is simple, but the vibration tube and the shell are integrated. External interference such as field vibration is transmitted to the vibration tube through the shell, thereby introducing interference, which makes the numerical error measured by the straight tube mass flowmeter large during use, greatly affecting the overall use efficiency of the device.
