Mass Flow Controllers Type 8626 are compact arrangement that control the mass flow rate of gases. They command the set flow velocity nonetheless of obstruction such as drop in pressure or interim resistance to flow. Flow regulator include a flow meter, an electronic module, as well as a proportional valve. Inline sensors function in the constant temperature anemometers mode. In this case, the electrical heating resistance and the measuring resistance are set to a constant temperature difference. Either resistances are directly in the gas stream; three more resistances are outside him. All resistances are combined in an electric bridge. The first resistance in the fluid flow measures the temperature of the liquid. The second, low resistance, is heated continuously to sustain an expressly specified surplus temperature relative to the fluid temperature. Owing to the fact that the resistances are disposed at once in the channel, the devices have splendid dynamics: the time for reaction when altering a given or actual value is hundredths of a millisecond. In addition, the sensor is almost not polluted.
