Mass Flow Controllers Type 8626 are compact arrangement that monitoring the mass flow of gases. They regulation the set flow velocity regardless of obstruction such as pressure drops or temporary flow resistance. Flow controllers include a flow meter, an electronic module, as well as a proportional valve. Inline sensors operate in the constant temperature anemometers mode. In that event, the electrical thermal resistance and the measuring resistance are adjusted 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 fluid temperature. Owing to the reality that the resistances are disposed directly in the channel, the instrument have excellent dynamics: the time for reaction when modifying a given or actual value is hundredths of a millisecond. In addition, the sensor is almost not polluted.
