Technical Field

The invention relates to the technical field of mass flowmeters, in particular to a straight tube type mass flowmeter.

Background

The volume of a fluid is a function of fluid temperature and pressure and is a dependent variable, while the mass of a fluid is a quantity that does not change with changes in time, space temperature, and pressure. As described above, the flow measurement value of a commonly used flowmeter, such as an orifice plate flowmeter, a laminar flow mass flowmeter, a turbine flowmeter, a vortex shedding flowmeter, an electromagnetic flowmeter, a rotor flowmeter, an ultrasonic flowmeter, and an oval gear flowmeter, is the volume flow rate of a fluid. The amount of fluid involved in activities such as scientific research, production process control, quality management, economic accounting, and trade transfers is generally mass. The mere measurement of the volumetric flow rate of a fluid using the above-described flow meter often fails to meet the requirements of a person and it is often desirable to try to obtain a mass flow rate of the fluid. Previously, the quality of the fluid can only be indirectly obtained by correcting, converting, compensating and the like after measuring parameters such as temperature, pressure, density, volume and the like of the fluid. The measuring method has a plurality of intermediate links, and the accuracy of mass flow measurement is difficult to ensure and improve. With the development of modern science and technology, some metering methods and devices for directly measuring mass flow are successively appeared, thereby promoting the progress of flow measurement technology.

The existing coil is large in mass, not only is not easy to install, but also is not beneficial to the balance of the whole weight, and the stability of the instrument is influenced.
