Closed loop constant flow rate flow source for high precision applications
In a typical lab environment, microfluidic experiments can often rely on external sources like pressurized air to drive media through the experiment. TTP Ventus manufactures the Disc Pump™, a small air pump, that can be used to build independent or even portable pressure driven flow sources for microfluidic applications. The advantage of a pressure driven flow source are the stable and non-pulsatile flow rates created over a large dynamic range. In order to leverage the full potential of such a flow source, the SLF3S-0600F liquid flow sensor for example can be used to create a small and highly integrated closed feedback loop system. By including the real time flow rate reading of the liquid flow sensor, the pump controller can drive the pump in exactly the right way to create the desired flow rates. Both, single and permanent use designs can be achieved by this Approach.
