Abstract: A gas distribution system may include a gas mass flow sensor with a resistive element configured to be heated, a thermally conductive shell surrounding the resistive element and heat-transfer control elements. The shell may include a leading surface oriented substantially orthogonal to a direction of gas flow. The heat-transfer control elements may be positioned to focus heat transfer from the resistive element through the leading surface of the shell so that a rate of heat transfer is independent from the variations in flow configuration.
