Burkert Type 8626 Mass Flow Controllers (MFC) are compact arrangement that control the mass flow rate of gases. They regulation the set flow rate regardless of interference including 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 constant temperature anemometers mode. In that event, the electrical thermal resistance and the measuring resistance are adjusted to a constant temperature difference. Either resistances are directly in the gas stream; and three resistances are out of it. All resistances are combined in an electric bridge. The first resistance in the fluid flow measures the temperature of the liquid. The second, low resistance, is constantly heated to maintain an expressly defined excess temperature relative to the temperature of theliquid. Owing to the fact that the resistances are disposed 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 almost not polluted.
