Liquid Mass Flow Meter - Digital Products - Model D2000iM

Fast Response Liquid Flow Controller
The Porter D2000i Series Liquid Mass Flow Controller is designed to address the need for fast, precise control of liquid precursors in semiconductor manufacturing processes. Closed-loop digital control circuitry, combined with an integral piezoelectric-actuated proportional control valve, offer response times of less than one second and stable control at low flows. A unique laminar bypass and sensor assembly provide accurate measurement with only a 5°C rise in fluid temperature.

Clean room assembly and all metal seal construction ensure high purity and leak integrity. The compact package size of the D2000i Series simplifies system integration.

A D2000i Series Liquid Mass Flowmeter is available for applications requiring flow monitoring only.
