Mass Flow Meter Operation - Focus on Microfluidic Control Technology

What's the working principle of the mass flow meter? Let's learn

The mass flow meter is a kind of thermal measurement, and the flow rate is measured by how many molecular masses are taken away by separate molecules. Because it is measured by a thermal type, 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 measurement instrument, which will be more widely used in petroleum processing, chemical engineering and other fields. It is believed that it will show great potential in promoting flow measurement. Mass flow meter can not control the flow, it can only detect the mass flow of liquid or gas, through analog voltage, current or serial communication output flow value. However, the mass flow controller is a meter that can detect and control at the same time. In addition to the measuring part, the mass flow controller itself also has an electromagnetic control valve or piezoelectric valve, so that the mass flow control itself constitutes a closed-loop system.

Used to control the mass flow of the fluid. The mass flow controller settings can be provided by analog voltages, analog currents, or by computers or PLCs.

This is the working principle of the mass flow meter. I hope everyone can take a good look and find out.
