Mass Flow Controllers Type 8626 are compact arrangement that monitoring the mass flow rate of gases. They control the set flow velocity nonetheless of interference such as pressure loss or temporary resistance to flow. Flow regulator consist of a flow meter, an electronic module, as well as a proportional valve. Inline sensors work in the CTA mode (constant temperature anemometers). In that event, the electrical thermal resist and the measuring resistance are set to a constant temperature difference. Both resistances are immediately in the gas stream; three more resistances are outside him. 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 constantly heated to maintain an expressly specified excess temperature relative to the temperature of thefluid. Owing to the reality that the resistances are inclined directly in the channel, the instrument have superb dynamics: the time for reaction when changing a given or actual value is hundredths of a millisecond. In addition, the sensor is practically not polluted.
