摘要

A microfluidic device for detecting a flow parameter, includes a channel configured within a base body, the channel including a first inlet for feeding a first fluid and a second inlet for feeding a second fluid so as to form a fluid stream having the first and second fluids within the channel, and further including an output for providing the fluid stream on the output side, a first feeder including a micropump associated with the first inlet for selectively feeding the first fluid to the channel, a second feeder associated with the second inlet for feeding the second fluid to the channel; and a detector for detecting, on the basis of a different physical property of the first fluid and the second fluid within the channel, a measurement value dependent on a current flow parameter of the first or second fluid.
