Mass Flow Controllers Type 8626 are compact arrangement that monitoring the mass flow rate of gases. They control the set flow velocity oblivious of hurdle for example pressure loss or interim resistance to flow. Flow controllers consist of a flow meter, an electronic module, and a proportional valve. Inline sensors work 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 directly in the gas stream; three more resistances are outside him. All resistances are joined in an electric bridge. The first resistance is gauge the temperature of the liquid. The second, low resistance, is constantly heated to maintain a clearly specified surplus temperature relative to the liquid temperature. Owing to the reality that the resistances are disposed straight away in the channel, the apparatus have splendid dynamics: the response time when altering a given or actual value is hundredths of a millisecond. Additionally, the sensor is practically not polluted.
