    High Grade Metal Flow Controllers
    MODEL 5100 SERIES


    Model 5100 Series Mass Flow Controller/Meter features weldless structure, metal seals, accurac y of ≤±1%, response of ≤±1 second and other basic performance con-ditions required for semiconductor process control, and additionally, has achieved a significant price reduction.

    Features
    - High accuracy and high response are achieved by the flow sen-sor with temperature- following current difference detection.
    - A normally-closed solenoid valve is employed.
    - A low leak rate is achieved by the weldless structure and metalseal.
    - The dead volume is reduced thanks to the diaphragm seat valve.-
    - The face-to-face and body dimensions and the wiring tie-inpoints are designed to facilitate replacement of devices made by other companies.
