MCDW Low Pressure Drop Bidirectional Mass Flow Controller

Sometimes a process is too complex for a standard mass flow controller. Alicat’s multi-directional mass flow controllers consolidate into one instrument what would otherwise require two or three separate devices.  Control flows into your flowing or closed process in one direction, and then reverse flow with multivariate measurement of flow, pressure and temperature in each direction. Or control flow into a closed process using pressure control while monitoring flow rates, and then vent the volume with no need for additional bleed valves.

The “Whisper” series bidirectional mass flow controllers with low pressure drop are ideal for controlling mass and volumetric flow rates when there is little available system pressure. Low pressure drop minimizes system impact, enabling flow control at near-atmospheric pressures and shortening system response times. Alicat’s MCDW brings the benefits of low pressure drop to our incredibly versatile MCD bidirectional flow controller.

Alicat’s MCDW series mass flow controllers feature dual digital and analog communications by default and can be ordered with Ethernet/IP, DeviceNet, Profibus or Modbus communications for easy integration into your digital industrial or laboratory network.  Other build options include your choice of display, downstream valve, and flow totalizers as well as performance options.  Need further customization?  Contact us and we’d be happy to help you build the instrument you need.

Each flow controller comes with a NIST-traceable calibration certificate and an Alicat operating manual.  Power supply sold separately.

The MCD standard configuration controls flow up to 160 PSIA.  The MCD series is also available with an optional “S” configuration for use with aggressive or corrosive gases (MCDS).
