The flexible structure was achieved by using polymer MEMS technologies. It has high linearity with a TCR of 0.0026K^{-1}, and a steady maximum value for the response time is reached within 7μs. The measuring distance from the tube entrance is 8.3 D (D=inner diameter of tube). This is much shorter than 64D, the theoretically calculated distance necessary for the formation of a fully-developed flow condition.}, pages = {622--625}, title = {Characteristics of On-Wall In Tube Thermal Flexible Mass-Flow Sensors}, year = {2006} }
