Bidirectional controller
15 December 2013
Alicat Scientific’s new MCD-Series Bidirectional Mass Flow and Pressure Controllers precisely and rapidly control mass flow rate, volumetric flow rate and absolute pressure of gases in two flow directions.
This flexible dual-valve design is reported to be the first of its kind, accommodating demanding process control requirements in gas analysis, leak testing and environmental applications.
With a dedicated inlet valve and a dedicated exhaust valve, a single MCD can control upstream and downstream flows, as well as positive pressure or backpressure in both open and closed systems.
