Burkert Type 8626 Mass Flow Controllers (MFC) are succinct devices that monitoring the mass flow of gases. They control the set flow rate nonetheless of hurdle for example drop in pressure or interim 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 this case, the electrical thermal resistance 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 electrical bridge. The first resistance in the fluid flow measures the temperature of the liquid. The second, low resistance, is constantly heated to maintain a clearly defined excess temperature relative to the liquid temperature. Owing to the reality that the resistances are situated straight away in the channel, the apparatus have splendid dynamics: the response time when changing a given or actual value is hundredths of a millisecond. Additionally, the sensor is practically not polluted.
