Mass Flow Controllers Type 8626 are succinct devices that control the mass flow of gases. They regulation the set flow rate oblivious of hurdle for example pressure loss or provisional resistance to flow. Flow controllers consist of a flow meter, an electronic module, and a proportional valve. Inline sensors operate in the CTA mode (constant temperature anemometers). In this case, the electrical thermal resistance and the measuring resistance are set to a constant temperature difference. Both 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 an expressly specified surplus temperature relative to the liquid temperature. Owing to the reality that the resistances are disposed directly in the channel, the apparatus have superb dynamics: the time for reaction when modifying a given or actual value is hundredths of a millisecond. In addition, the sensor is practically not polluted.
