Mass Flow Controllers Type 8626 are succinct arrangement that control the mass flow of gases. They control the set flow velocity regardless of interference such as drop in pressure or interim resistance to flow. Flow regulator include a flow meter, an electronic module, and a proportional valve. Inline sensors work in the constant temperature anemometers mode. In that event, the electrical thermal resist and the measuring resistance are adjusted to a constant temperature differentiation. Both resistances are immediately in the gas stream; three more resistances are outside him. All resistances are joined 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 sustain a clearly defined excess temperature relative to the temperature of theliquid. Due to the reality that the resistances are inclined at once in the channel, the apparatus have superb dynamics: the time for reaction when modifying a given or actual value is hundredths of a millisecond. Additionally, the sensor is almost not contaminated.
