Burkert Type 8626 Mass Flow Controllers (MFC) are compact arrangement that control the mass flow of gases. They regulation the set flow velocity nonetheless of hurdle such as pressure loss or provisional flow resistance. Flow regulator consist of a flow meter, an electronic module, and a proportional valve. Inline sensors function in the CTA mode (constant temperature anemometers). In this case, the electrical heating resist 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 united in an electrical bridge. The first resistance in the fluid flow measures the temperature of the liquid. The second, low resistance, is heated continuously to maintain a clearly specified surplus temperature relative to the fluid temperature. Due to the fact that the resistances are inclined directly in the channel, the instrument have splendid dynamics: the time for reaction when modifying a given or actual value is hundredths of a millisecond. Additionally, the sensor is practically not polluted.
