Features of FDC-300 Series Mass Flow Controller and Meters
Long-term Stability and Accuracy
Unique thermal sensing technology can provide excellent signal-to-noise ratio performance to improve measurement and control accuracy under low set-point conditions Long-term zero point stability, annual variation is less than 0.2% of full scale.
Multiple Communication
This series is equipped with a digital circuit system, which is compatible with analog signals 0~5V/4~20mA, but also can communicate through RS-485 digital communication. The multi-protocol communication interface can simplify the integration operation.
Resistant to Toxic and Corrosive Gases
The capillary thermal temperature difference sensor effectively isolates the erosion of corrosive gases. The substrate is made of 316L stainless steel, and the chemical corrosion-resistant valve has super adaptability to toxic and corrosive gases.
Wide Pressure and Flow Range
The flow range of this series can be from 3 sccm to 2500 lpm, and the pressure resistance rating and working pressure are also up to 500 psi/100 bar. The high pressure differential solenoid valve is suitable for flow measurement and control.
Modular Design for Easy Maintenance
A user-accessible service port simplifies installation, troubleshooting, and diagnostics without interfering with flow controller operation, and a durable, stable metal housing prevents damage to the unit during installation.
Application of FDC-300 Series Mass Flow Controller and Meters
Petrochemical Reaction System
In order to optimize a chemical reaction, the best combination of compounds must be found and injected into the reactor in an optimal ratio. A certain pressure and temperature can be maintained, and a catalyst can be added to accelerate the reaction. When the reactor is pressurized, the incoming reaction gases must always be accurately measured.
Gas Chromatographs Instrument
Gas chromatography is a widely used analytical technique for qualitative and quantitative analysis of samples. The sample is injected through the sample injector in the carrier gas flow. Gas flow is controlled using a high-precision mass flow controller. The sample to be analyzed will pass through a stationary heated column, eluting the analytes at different times.
Material Preparation Process Applications
In the preparation of some new materials, such as graphene and diamond crystals, chemical vapor deposition is usually used. The gas mass flow controller can accurately control the gas flow in the reaction chamber of the equipment to improve the purity of the prepared crystals. Thereby ensuring product quality.

Ar Protection System for Steelmaking
There must be sufficient supply of argon in the process of smelting steel. On the other hand, since argon is expensive, the supply must be limited and well controlled. In addition, when the pressure in the converter changes, the air supply control equipment must be able to compensate for this. Gas lines and shut-off valves are to be arranged by the customer.
