How it Works

Modes
Pressure Mode:  A fluid vessel is pressurized or evacuated according to a user-defined pressure profile.  Fluid is either displaced from a vessel (positive pressure delivery) or alternatively is pulled into a vessel (negative pressure delivery).  The DUO can imperceptibly change between positive and negative pressure fluid delivery.

Flow Rate Mode:  The DUO adjusts the vessel pressure as needed to achieve the user's desired flow rate profile.  Flow rate measurement is provided with a "+" or a "-" to represent the flow direction.


Integrated Components 
  • Flow sensors (optional)
  • Pressure Sensors
  • On-board microprocessor for fast response
Control​
  • PC Software - Synchronize two to eight independently controlled fluid channels.  Fully programmable fluid delivery.
  • LabVIEW VI
  • Optional RS-232 module
Data Logging
  • Both pressure and flow rate are logged.

Screen Capture of PneuWave Pump Software
Software Screen Capture demonstrating that flow (blue) and pressure (red) can indiscernibly switch between positive and negative modes. Fluids can be easily manipulated in either direction, or even oscillated back and forth, within the same channel. Furthermore a zero flow rate can be actively held for stop flow experiments.
