Burkert Type 8626 Mass Flow Controllers (MFC) are succinct arrangement that inspection the mass flow of gases. They regulation the set flow rate oblivious of interference for instance drop in pressure or interim flow resistance. Flow regulator include a flow meter, an electronic module, as well as a proportional valve. Inline sensors work in the CTA mode (constant temperature anemometers). In that event, the electrical thermal resist and the measuring resistance are adjusted to a constant temperature differentiation. Either resistances are directly in the gas stream; three more resistances are outside him. All resistances are joined in an electric bridge. The first resistance is measures the temperature of the fluid. The second, low resistance, is constantly heated to maintain a clearly specified excess temperature relative to the fluid temperature. Owing to the fact that the resistances are situated at once in the channel, the instrument have splendid dynamics: the time for reaction when changing a given or actual value is hundredths of a millisecond. In addition, the sensor is practically not polluted.
