Mass Flow Controllers Type 8626 are compact devices that control the mass flow of gases. They control the set flow velocity nonetheless of interference including drop in pressure or temporary flow resistance. Flow regulator include 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 thermal resist and the measuring resistance are adjusted to a constant temperature differentiation. Either 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 an expressly specified excess temperature relative to the liquid temperature. Due to the reality that the resistances are disposed directly in the channel, the apparatus have splendid dynamics: the response time when modifying a given or actual value is hundredths of a millisecond. Additionally, the sensor is practically not polluted.
