韩国LINETECH气体质量流量控制器，超大流量2500升每分钟，

MS3700VA气体质量流量控制器英文使用说明。

韩国原装进口    主体材质：不锈钢316L    产品坚固耐用，耐腐蚀。

Mass Flow Controller,MS3700 Series (Analogue).The M-SERIES of Line Tech Mass Flow         Controller (MFC) is a device designed for accurately measuring and controlling flow rates of gases. This manual is intended to provide the user with all the information to install successfully.

Mass Flow Controller is classified into three parts. (Body, P.C.B, Control valve) .This harmony produces stable gas flow of rate as well djusting gas pressure continuously.

Installation

The M-Series of Line Tech inlet and outlet connection standard is V.C.R and S.W.G type.Install the equipment with consideration to the given structure and strength condition.Be sure to clean the inside of pipe line by blowing high-pressured gas before connecting to MFC.

※ Cautions When Installing ※

▶Check gas flow direction.

▶When using corrosive or inflammable gas, completely rid the system of moisture or leakage with N2 gas before the usage.

▶Do not install the equipment in the presence of possible mechanical damage or vibration.

Operation

 ◎Warm up time ◎

1) After installing, warm up equipment for 30 minutes to stabilize the temperature of the sensor.

2) Before supplying gas, adjust the zero point to less than 0.2%

3) Supply gas.

4) Check for any leakage.

5) Operate.

◎Setting up the Zero Point ◎

▶The Zero Point may change depending on the surrounding's temperature installation

structure.

▶Approximately 30 minutes after supplying power, when installed according to the

correct environment and application conditions, set up the final Zero Point.
