Mass Flow Controllers Type 8626 are compact arrangement that control the mass flow of gases. They regulation the set flow velocity regardless of interference such as pressure loss or provisional flow resistance. Flow regulator consist of a flow meter, an electronic module, as well as a proportional valve. Inline sensors work in the constant temperature anemometers mode. In that event, the electrical heating resist and the measuring resistance are set to a constant temperature differentiation. Either resistances are immediately in the gas stream; and three resistances are out of it. All resistances are combined in an electrical bridge. The first resistance in the fluid flow measures the temperature of the liquid. The second, low resistance, is heated continuously to maintain a clearly defined surplus temperature relative to the liquid temperature. Due to the reality that the resistances are disposed at once in the channel, the instrument have superb dynamics: the time for reaction when changing a given or actual value is hundredths of a millisecond. Additionally, the sensor is practically not polluted.
