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

Mass flow meter is a new type of direct measurement of the fluid mass flow measurement instrument inside a closed pipeline. Its structure is generally composed of a signal measurement sensor and a signal converter.

Because mass flowmeters have the ability to directly measure fluid bead mass flow, high measurement accuracy, wide application range, low installation requirements, reliable instrument operation, and low maintenance rate, mass flow meters have been widely used in petroleum, chemical, metallurgical, and thermal applications. , Electricity, food and other fields of traffic measurement. The mass flow meter uses a thermal sensing method to measure the flow rate by separating the molecular mass away from the molecule. Because it is measured by a thermal method, the measurement result is not affected by the temperature and pressure of the gas.

Mass flow meter is a more accurate, fast, reliable, efficient, stable, and flexible flow measurement instrument. In the petroleum processing, chemical and other fields will be more widely used, I believe that will show great potential in promoting flow measurement. The mass flow meter can not control the flow, the mass flow meter can only detect the mass flow of liquid or gas, and output the flow value through analog voltage, current or serial communication. However, mass flow meters are instruments that can detect and control at the same time. In addition to the measurement section, the mass flowmeter itself also has an electromagnetic or piezoelectric valve.

This way the mass flow meter itself forms a closed-loop system for controlling the mass flow of the fluid. Mass flow meter settings can be provided by analog voltages, analog currents, or computers, PLCs.
Mass flowmeters can also be used as high-precision online densitometers to measure fluid real-time density and temperature. At the same time, other parameters such as volume flow, medium content, and concentration can also be calculated. The mass flowmeter directly measures the mass flow of the medium through the flowmeter. It also measures the density of the medium and indirectly measures the temperature of the medium. Since the transmitter is a smart meter with a single-chip microcomputer as the core, more than ten parameters can be derived for the user according to the above three basic quantities. Mass flow meter is a new generation of flow meter with flexible configuration, powerful function and high cost performance.
