Abstract

The design and structure of a fluidic concentration metering device with a full dynamic range utilizing micro-machined thermal time-of-flight sensing elements is exhibited in this disclosure. With an additional identical sensing chip but packaged at the different locations in the measurement fluidic chamber with a closed conduit, the device can simultaneously measure the fluidic concentration and the fluidic flowrate. With a temperature thermistor integrated on the same micro-machined thermal sensing chip, the disclosed device will be able to provide the key processing parameters for the fluidic applications.
