Mass Flow Controllers Type 8626 are compact arrangement that control the mass flow of gases. They control the set flow velocity irrespective of obstruction such as pressure drops or provisional flow resistance. Flow controllers consist of a flow meter, an electronic module, as well as a proportional valve. Inline sensors operate in the constant temperature anemometers mode. In that event, the electrical heating resistance and the measuring resistance are adjusted to a constant temperature differentiation. Both resistances are immediately in the gas stream; three more resistances are outside him. All resistances are joined in an electric bridge. The first resistance is gauge the temperature of the liquid. The second, low resistance, is constantly heated to sustain an expressly specified excess temperature relative to the fluid temperature. Due to the reality that the resistances are disposed at once in the channel, the apparatus have excellent dynamics: the time for reaction when modifying a given or actual value is hundredths of a millisecond. In addition, the sensor is practically not polluted.
