Abstract: A micro flow sensor based on the thermotransfer principle is developed here. The sensor consists of a micro heater with a micro thermocouple downstream of the heater. The flow sensor is microfabricated in a three step process: (a) micro heater and thermocouple fabrication, (b) microchannel fabrication and (c) system integration. The micro flow sensor was characterized using a mixture of 50% methanol and 50% water. The flow rate in the microchannel was controlled using a syringe pump. The sensor was calibrated using a pulse heat input. The results show that the sensor was sensitive for flow in the range 0.5μl/min to 0.7ml/min.
Description: This paper was presented at the 3rd Micro and Nano Flows Conference (MNF2011), which was held at the Makedonia Palace Hotel, Thessaloniki in Greece. The conference was organised by Brunel University and supported by the Italian Union of Thermofluiddynamics, Aristotle University of Thessaloniki, University of Thessaly, IPEM, the Process Intensification Network, the Institution of Mechanical Engineers, the Heat Transfer Society, HEXAG - the Heat Exchange Action Group, and the Energy Institute.
