Burkert Type 8626 Mass Flow Controllers are compact arrangement that monitoring the mass flow rate of gases. They control the set flow velocity regardless of obstruction such as drop in pressure or provisional flow resistance. Flow controllers 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 thermal resistance and the measuring resistance are set to a constant temperature differentiation. Both resistances are immediately in the gas stream; and three resistances are out of it. All resistances are joined in an electrical bridge. The first resistance is gauge the temperature of the liquid. The second, low resistance, is constantly heated to maintain a clearly specified excess temperature relative to the liquid temperature. Due to the fact that the resistances are situated at once in the channel, the instrument have splendid dynamics: the response time when changing a given or actual value is hundredths of a millisecond. Additionally, the sensor is practically not polluted.
