Burkert Type 8626 Mass Flow Controllers (MFC) are succinct arrangement that inspection the mass flow rate of gases. They control the set flow velocity regardless of obstruction for instance pressure drops or interim flow resistance. Flow regulator include 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 resist and the measuring resistance are adjusted to a constant temperature difference. Both resistances are immediately in the gas stream; three more resistances are outside him. All resistances are united in an electrical bridge. The first resistance is measures the temperature of the fluid. The second, low resistance, is constantly heated to maintain a clearly defined excess temperature relative to the temperature of thefluid. Due to the fact that the resistances are situated straight away in the channel, the instrument have splendid dynamics: the response time when changing a given or actual value is hundredths of a millisecond. In addition, the sensor is practically not polluted.
