A sensor method and system are disclosed. A fluid flow sensor can be provided, which measures the thermal conductivity of a fluid. The sensor itself can be configured to comprimise one or more sensing element associated with sensor substrate. A heater can be associated with a said sensor wherein said heater provides heat to said fluid. A film component can also be provided that that isolates said fluid from said heater and said sensor, such that said film component conducts heat in a direction from said heater to said sensor, thereby forming a thermal coupling between said sensor, said heater and said fluid, which permits said sensor to determine a composition of said fluid by measuring thermal conductivity thereof without undersired losses of heat in other directions. The film component can be configured on or in the shaped of a tubing or a flow channel. |
