Burkert Type 8626 Mass Flow Controllers are compact arrangement that control the mass flow of gases. They regulation the set flow velocity regardless of hurdle such as pressure drops or temporary flow resistance. Flow regulator consist of a flow meter, an electronic module, as well as 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 difference. Both resistances are directly in the gas stream; three more resistances are outside him. All resistances are united in an electrical bridge. The first resistance is gauge the temperature of the liquid. The second, low resistance, is heated continuously to maintain a clearly specified surplus temperature relative to the temperature of thefluid. Due to the reality that the resistances are situated straight away in the channel, the instrument have splendid dynamics: the time for reaction when modifying a given or actual value is hundredths of a millisecond. In addition, the sensor is almost not contaminated.
