Burkert Type 8626 Mass Flow Controllers (MFC) are succinct devices that monitoring the mass flow of gases. They regulation the set flow rate oblivious of interference such as pressure drops or provisional flow resistance. Flow controllers consist of a flow meter, an electronic module, and a proportional valve. Inline sensors function in the CTA mode (constant temperature anemometers). In that event, the electrical heating resistance and the measuring resistance are adjusted to a constant temperature difference. Either 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 liquid. The second, low resistance, is constantly heated to sustain an expressly defined excess temperature relative to the temperature of thefluid. Owing to the fact that the resistances are situated directly in the channel, the instrument have superb dynamics: the response time when changing a given or actual value is hundredths of a millisecond. In addition, the sensor is almost not polluted.
