Mass Flow Controllers Type 8626 are succinct devices that inspection the mass flow rate of gases. They control the set flow velocity nonetheless of interference for instance pressure loss or temporary 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 this case, the electrical heating resistance and the measuring resistance are set to a constant temperature difference. Both resistances are immediately in the gas stream; and three resistances are out of it. 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 a clearly defined excess temperature relative to the temperature of theliquid. Owing to the fact that the resistances are inclined at once in the channel, the devices have splendid dynamics: the time for reaction when changing a given or actual value is hundredths of a millisecond. Additionally, the sensor is practically not polluted.
