System name: Two-component dynamic gas distribution system
System model: GDS-D2
use
The system is used to prepare multi-component standard gases which are gaseous at normal temperature and can be widely used in sensor multi-point calibration and other research.
system structure
The system is mainly composed of the following parts:
Two-component dynamic gas distribution system
Computer and operating software (can also use LED touch screen, then do not need to be equipped with computer and software part)
The components of the system are as follows:
Two-component dynamic gas distribution system
The system uses the advanced measurement and control technology in the world at present, the equipment is stable and reliable, and the preparation accuracy is high. Fully automatic control, simple and reliable operation. The equipment is integrated into one chassis. The appearance is simple and beautiful. The main equipment includes: mass flow controller, check valve, stop valve, gas mixing pipeline, etc. Due to the existence of methane, ethane, ethylene, acetylene and other flammable and explosive dangerous media. The air distribution system is designed to be installed separately from the circuit control part, and fans are installed at places where flammable gas leakage may exist to ensure air circulation and prevent flammable gas leakage. Ensure systems and personnel *.
The system is designed as a two-component gas distribution mode, one of which is diluent gas, the other is source gas, and the source gas is standard bottle gas.
The system is equipped with 2 * inlet mass flow controllers, which can realize the mixing ratio of 2 component gases.
There are as many as forty or fifty gases in the system database, which can be directly selected by computer when used.
Mixed gas flow rate: 2 L* min.
Gas distribution channel: 2 ways

2. gas circuit
The gas path of the whole system adopts anti-corrosion anti-adsorption inner surface polishing treatment polytetraethylene pipe
3. rotameter
Easy to use The excess gas can be discharged directly by adjusting the rotor flow meter
4. Computer and system software
1)The gas distribution system is operated via a touch screen.
2) Two-component gas distribution software
The gas distribution system can be equipped with cylinders and corresponding ports according to requirements. And can be distributed through flow mode and concentration mode. Through automatic calculation by software, the gas mass flow controller automatically adjusts and controls the gas flow to achieve the gas ratio concentration requirements.
