Knowledge of Mass Flowmeter Hardware Failures - Focus on Microfluidic Control Technology

The mass flow meter is a commonly used flow measuring instrument that can directly measure the mass flow rate of the medium passing through the flow meter, and has the advantages of high measurement accuracy, good sensitivity, flexibility of use, and high reliability. So what is the measurement principle of this flowmeter?
Measuring principle of mass flow meter:
1 The flowmeter uses the thermal measurement to measure the flow rate by the molecular mass of the separated molecules. Because it is measured by the sensible heat, it will not affect the measurement result due to the change of gas temperature and pressure. At the same time, it is also a relatively accurate, fast, reliable, efficient, stable and flexible flow measurement instrument, which will be more widely used in petroleum processing, chemical industry, etc. It is believed that it will show great potential in promoting flow measurement.
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. Because of its flexible configuration, powerful functions and high cost performance, this flow meter 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.
As a highly sophisticated instrument, the mass flow meter not only needs to strictly comply with its requirements during the manufacturing and use process, but also must pay special attention to the maintenance in the later stage so as not to let the flow meter retire early.
