Abstract
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 comprise one or more sensing element associated with a sensor substrate. A heater can be associated with 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 undesired losses of heat in other directions. The film component can be configured on or in the shape of a tubing or a flow channel.
