Applications
Gas flow controllers with ultra-large flow rates are generally used in production enterprises and factories. They can accurately control the inflow and outflow of gas, achieve higher processing requirements, and save energy costs.
Sino-Inst’s thermal gas mass flow controllers and mass flow meters are made using a new manufacturing process. They have the advantages of fast response speed, high accuracy, stable flow control, and good linearity. They are suitable for controlling most inert and partially corrosive gases.
Widely used in high-tech companies in industries such as petrochemicals, university laboratories, research institutes, aerospace, food manufacturing, pharmaceutical manufacturing, thermal power, nuclear power, natural gas filling stations, semiconductors, solar energy, and LCD panel manufacturing.
Application of gas mass flow controller in heat treatment field
A heat treatment equipment company is a professional company specializing in ion nitriding process research and equipment production. It has accumulated rich experience in the design and production of glow ion nitriding furnaces. The main products are LD series ion nitriding furnaces, LDMC series pulsed ion nitriding furnaces, and ion nitriding furnaces with auxiliary heating.
The gas supply system consists of an ammonia bottle, an ammonia pressure reducer, a gas mass flow meter and a gas pipeline. The equipment is equipped with two flow meters, which are used for ammonia flow regulation and carburizing gas flow regulation respectively. The two gases are mixed and passed into the furnace after passing through the flow meter. The nitrogen and carbonitriding process (soft nitriding) can be achieved by adjusting the flow ratio.
Solution: Our company customized the gas mass flow controller for the enterprise according to the process requirements of this product. It is not affected by temperature, pressure and other conditions. It has been successfully installed on the equipment to accurately control the flow of the two gases. It is sensitive and has a fast response speed, which realizes the mixing ratio of the two gases. Thereby improving the carbonitriding process. The customer said that he would gradually replace the original flow meter with our company’s gas mass flow controller.
What is a gas flow controller?
The Mass Flow Controller (MFC) is an instrument used to accurately measure and control gas flow. It consists of three parts: a flow sensor, a control circuit, and an actuator.
The working principle of this device is based on fluid mechanics and heat transfer principles. The mass flow sensor measures the pressure difference and temperature change when the gas flows through the pipeline, and then calculates the mass flow rate of the gas. The gas flow rate is adjusted by controlling the valve to keep it within the set range.
