Measurement principle of mass flow meter - focus on microfluidic control technology

The mass flow meter is an important flow meter. Mass flow meters are measured using thermal measurements. Mass flowmeter is a highly integrated product of light, machine, electricity, computer and many basic disciplines. It is sensitive to new technologies. Mass flowmeter is one of the products with faster replacement speed in modern industrial products.
The basic principle of the mass flow meter is to use an external heat source to heat the measured fluid in the pipeline. The thermal energy flows with the fluid and reflects the mass flow of the fluid by measuring the change in heat (temperature) caused by the fluid flow.
Measuring principle of mass flow meter:
The 1 mass flow meter uses the thermal measurement to measure the flow rate by the molecular mass of the separated molecules. Because the mass flow meter is measured by the thermal method, it will not be affected by the change of gas temperature and pressure. The result of the measurement. At the same time, the mass flow meter is also a relatively accurate, fast, reliable, efficient, stable and flexible flow measuring instrument. It will be more widely used in petroleum processing, chemical industry, etc. It is believed that the mass flow meter will show great in driving flow measurement. potential.
2 mass flowmeter can also measure the density of the medium and indirectly measure the temperature of the medium. Since the transmitter is a smart meter with the single chip as the core, more than ten parameters can be derived for the user according to the above three basic quantities. Due to the flexible configuration, powerful function and high performance-price ratio of the mass flow meter, it is a new generation flow meter.
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 the vapor and air streams are also proportional to the mass flow. Strict control of product quality, accurate costing, and fuel quantity control for aircraft and missiles also require precision. Therefore, the mass flow meter is an important flow measuring instrument.
