What is a gas flow controller?
A gas mass flow controller is a high-precision, high-stability flow control device. It can accurately measure and stably control the gas mass flow within the set flow range. It is also called a gas mass flow controller (MFC). Compared with traditional volume flow controllers, MFC is not affected by changes in gas temperature and pressure and can more accurately reflect the actual flow of the gas.
Digital Gas Mass Flowmeter-Mass Flow Controller working principle
The excellent accuracy, robustness and reliability of gas mass flow controllers come from our unique sensor probes. The sealed probe consists of two sensing elements, a speed sensor and a temperature sensor, which can automatically correct the effects of temperature and pressure changes.
The instrument circuit heats the speed sensor to a constant value above the gas temperature and then measures the cooling effect of the gas flow. The flow rate is calculated based on the principle that the electrical power consumed to maintain a constant temperature difference is proportional to the mass flow rate of the gas.
Both sensors are standard grade platinum resistance temperature detectors (RTDs). Platinum RTD wire is wrapped around a strong ceramic mandrel for strength and reliability. The entire sensor is sealed in a 316 stainless steel packaging case.
Digital Gas Mass Flowmeter-Mass Flow Controller Application
Digital Gas Mass Flowmeter – A mass flow controller (abbreviated as MFC) is used for precise measurement and control of the mass flow of gases.
They play an important role in scientific research and production in various fields such as semiconductor and integrated circuit industry, special materials discipline, chemical industry, industry, medicine, environmental protection and vacuum lamps.
Typical applications include:
- Electronic process equipment, such as diffusion, epitaxy, CVD, oxidation, plasma etching, sputtering, and ion implantation;
- Coating equipment, optical fiber smelting, micro-reaction devices, gas mixing and distribution systems, capillary measurement, gas chromatograph, and other analytical instruments;
What is the difference between mass flow and volume flow?
Volume flow refers to the flow in which the amount of fluid is expressed in volume. Volume flow is expressed by the formula: qv=V/t=u×A, where: qv is the volume flow, m3/s; V is the unit flow volume, m3; t is the unit time, s; u is the average flow velocity in the pipe, m/s; A is the cross-sectional area of the pipe, m2.
Mass flow refers to the flow in which the amount of fluid is expressed in mass. Mass flow can be expressed by the formula: qm=m/t=ρ×u×A, where qm is the mass flow, kg/s; m is the unit fluid mass, kg; ρ is the fluid density, kg/m3; t is the unit time, s; u is the average flow velocity in the pipe, m/s; A is the cross-sectional area of the pipe, m2.
How to convert volume flow and mass flow:
- If the mass flow of the flow is known and needs to be converted to volume flow, the following formula can be used: qv=qm/ρ, where qv is the volume flow, m3/s; qm is the mass flow, kg/s; ρ is the fluid density, kg/m3.
- If the volume flow of the fluid is known and needs to be converted to mass flow, the formula can be used: qm=qv×ρ
