Mass Flow Controllers Type 8626 are compact arrangement that inspection the mass flow of gases. They command the set flow rate regardless of interference including drop in pressure or provisional resistance to flow. Flow regulator consist of a flow meter, an electronic module, and a proportional valve. Inline sensors function in the constant temperature anemometers mode. In that event, the electrical heating resistance and the measuring resistance are set to a constant temperature difference. Either resistances are directly in the gas stream; and three resistances are out of it. 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 constantly heated to sustain an expressly specified excess temperature relative to the liquid temperature. Owing to the reality that the resistances are inclined straight away in the channel, the instrument have superb dynamics: the time for reaction when altering a given or actual value is hundredths of a millisecond. Additionally, the sensor is almost not polluted.
