Mass Flow Controllers Type 8626 are succinct devices that monitoring the mass flow of gases. They control the set flow rate oblivious of interference for instance pressure drops or temporary resistance to flow. Flow regulator consist of a flow meter, an electronic module, as well as a proportional valve. Inline sensors function in the constant temperature anemometers mode. In that event, the electrical thermal resist and the measuring resistance are adjusted 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 electric bridge. The first resistance in the fluid flow measures the temperature of the liquid. The second, low resistance, is constantly heated to maintain a clearly specified excess temperature relative to the liquid temperature. Owing to the fact that the resistances are located at once in the channel, the instrument have excellent dynamics: the time for reaction when altering a given or actual value is hundredths of a millisecond. Additionally, the sensor is practically not polluted.
