What is the measurement principle of mass flow meter

What is the measurement principle of mass flowmeter? Mass flowmeter is a commonly used flow measuring instrument, which can directly measure the mass flow of the medium passing through the flowmeter. It has the advantages of high measurement accuracy, good sensitivity, flexible use and high reliability. So what is the measurement principle of this kind of flowmeter? The measurement principle of mass flowmeter: ①The flowmeter adopts thermal measurement, and the flow rate is measured by the molecular mass taken away by the split molecules, because it uses thermal Measurement, so the measurement results will not be affected by changes in gas temperature and pressure. At the same time, it is also a relatively accurate, fast, reliable, efficient, stable and flexible flow measuring instrument, which will be widely used in petroleum processing, chemical industry and other fields, and it is believed that it will show great potential in promoting flow measurement. ②The mass flowmeter can also measure the density of the medium and indirectly measure the temperature of the medium. Since the transmitter is an intelligent instrument with a single-chip microcomputer as the core, it can derive more than a dozen parameters for users to use based on the above three basic quantities. Because of its flexible configuration, powerful functions, and high performance-price ratio, this flowmeter is a new generation of flowmeter. ③ With the improvement of automation level, many production processes have put forward new requirements for flow measurement. The chemical reaction process is controlled by the quality of the raw materials. The heating and cooling effects of steam and air flow are also proportional to the mass flow rate. Strict control of product quality, accurate cost accounting, machine and accurate fuel quantity control are also required. Therefore, the mass flow meter is an important flow measuring instrument. As a highly precise instrument, the mass flowmeter not only requires us to strictly abide by its requirements during the process of manufacture and use, but also must pay special attention to the later maintenance so as not to make the flowmeter retire early.
