Owing to its origins, the field of microfluidics is closely associated with the biosciences and related technologies, such as cell sorting, cell manipulation and DNA analysis. Microfluidics is also relevant in other miniaturized systems that use liquids; for example, microscopic chemical reactors and micro fuel cells for portable energy generation.
In all these emerging application areas, the precise monitoring and control of liquid flows is crucial to the reliable operation of the respective device. With a tiny form factor of just 10 x 10 mm2, Sensirion’s LPG10 flow sensor offers outstanding accuracy and speed in the measurement of extremely low flow rates. The sensor consists of a planar microfluidic glass substrate and enables extremely compact integration in any fluidic system. The proven microthermal measurement method in an innovative design enables flow measurements of just a few milliliters down to single microliters per minute, or even lower. Glass as the only wetted material guarantees optimal compatibility with biological and pharmaceutical processes. The sensor provides a direct and highly precise measurement of the flow rate at every relevant point in the fluidic system. The reliable detection of common errors, such as clogging, air bubbles or leaks, is incorporated of course.
