Application And Features

    Mass Flow Meter (MFM) accurately measures mass flow rates, Mass Flow Controller (MFC) accurately measures and controls mass flow rates despites gas volume fluctuated due to pressure or temperature changes. Which is widely applied in the fields as: semiconductor and IC fabrication, special materials science, chemical industry, petrolic industry, pharmaceutical industry, environmental protecting and vacuum system researching, etc.. The typical applications include: microelectronic process equipment such as diffusion, oxidation, epitaxy, CVD, plasma etching, sputtering, ion implantation; vacuum deposition equipment, optical fiber melting, micro-reaction equipment, mixing & matching gas system, capillary flow control system, gas chromatograph and other analytical instruments.

    MD-05 series MFM & MFC bring the high accuracy, excellent repeatability, quick response, soft-start, better reliability, wide variety ranges of operation pressure (good operation in high pressure and vacuum situations), simple convenient operation, flexible installation, possible connecting with PC to carry out automatic control to the users' system. MD-05 series better be connected together with MD-06 Readout Box series, the cable connection is showing as following (Figure 1):

Technical Parameters

High Precision Environmental Protecting / Vacuum System Researching Digital Gas Mass Flow Controller and Meter
Notes :

MFC/MFM is calibrated by N2 as a standard gas.

Units:                            SCCM  (Standard Cubic Centimeter/Min);

                                     SLM    (Standard Liter/Min)

Standard Situation:    Tem - 273.15K ( 0 ºC );

Air Pressure -          101325 Pa  (760mm Hg)

F.S :                           Full Scale


    The MFM consists of flow sensor, flow-splitter bypass and flow amplifying circuit, add control valves and PID control circuit to MFM will compose a MFC. The following figure is exactly showing the structure of MD-0519C MFC after opening up its overall:
