Burkert Type 8626 Mass Flow Controllers (MFC) are compact devices that monitoring the mass flow rate of gases. They regulation the set flow velocity regardless of interference 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 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 liquid temperature. Due to the fact that the resistances are disposed directly in the channel, the apparatus have splendid dynamics: the time for reaction when altering a given or actual value is hundredths of a millisecond. Additionally, the sensor is practically not polluted.
