The FLOW UNIT and FLOW UNIT+ are bidirectional microfluidic flow sensors compatible for stand-alone use with the Line Up™ controller or other microfluidic control systems such as the MFCS™ series using the Flowboard hub. Available in multiple low rate ranges, the FLOW UNIT and FLOW UNIT + Microfluidic Flow Sensor allows for pressure regulation using the DFC (Direct Flow Control) algorithm to monitor or control the system by flowrate instead of pressure.
