AMFC
The SMC Mass Flow Meter (AMF) and Controllers (AMFC) are a combination of our proven thermal mass flow technology and intelligent flow controller, which provides user friendly control functions to ensure excellent performance and fast control even under varying process conditions. Superior control settling time, no dead time and other functions are the enhanced features that ensure stable and continuous gas flow.
FEATURES

Direct mass flow measurement of any gas or mixture.

Single and multi-valve group configurations provide full control over range of 0.01~ 7 SCFM (5~200 slpm).

Tracking of gas flow rate over a turndown ratio of at least 20:1.

Options: controller with or without display.

Flow display : 4 digital characters.

Equivalent effective nitorogen or actual gas calibration.

low cost, superior value.
