The importance of mass flow meters can be seen everywhere - focus on microfluidic control technology

Mass flowmeter is a new type of direct measurement of fluid mass flow measurement instrument in closed pipeline. Its structure is generally composed of two parts: signal measurement sensor and signal converter.

Because the mass flow meter has the characteristics of direct measurement of fluid bead mass flow, high measurement accuracy, wide application range, low installation requirements, reliable instrument operation and low maintenance rate, mass flowmeter has been widely used in petroleum, chemical, metallurgy and heat. , flow measurement in the fields of electricity, food, etc. The mass flow meter uses a thermal measurement to measure the flow rate by the molecular mass of the separated molecules. Because it is measured by the sensible heat, it does not affect the measurement result due to changes in gas temperature and pressure.

Mass flow meter is a more 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 it will show great potential in promoting flow measurement. Mass flow meters cannot control flow. Mass flow meters can only detect the mass flow of liquid or gas, and output flow values by analog voltage, current or serial communication. However, the mass flow meter is a meter that can detect both at the same time and can be controlled. In addition to the measuring part, the mass flow meter itself has an electromagnetic regulating valve or a piezoelectric valve.

Such a mass flow meter itself constitutes a closed loop system for controlling the mass flow of the fluid. The set value of the mass flow meter can be provided by analog voltage, analog current, or computer or PLC.
The mass flow meter can also be used as a high precision online density meter to measure the real-time density and temperature of the fluid. At the same time, other parameters such as volume flow, medium content, concentration, etc. can be calculated. The mass flow meter directly measures the mass flow rate of the medium passing through the flow meter, and also measures the density of the medium and indirectly measures 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. The mass flow meter is flexible, powerful, and cost-effective. It is a new generation flow meter.
