There are many reasons why it is important to identify the liquid in a microfluidic system. In this thermal conductivity case study, we take a closer look at one option to solve this challenge.
Membrane-based micropumps like the mp6 micropump can be controlled by the frequency (how often per second the membrane is actuated) and the driving voltage of the actuating elements (controlling the stroke of the membrane). Both parameters need to be adjusted to match the viscosity of the liquid and the desired flow rate. Especially applications in which different liquids are handled by the same pump profit from automating this manual step.
For that purpose, this Case Study is demonstrating that our mp6 micropump in conjunction with Sensirion’s SLF3C-1300F sensor can recognize the liquid. This creates the possibility to automatize the pump-parameter-adjustment.
