Mass Flow Controllers Type 8626 are succinct arrangement that inspection the mass flow rate of gases. They control the set flow velocity regardless of interference such as pressure drops or provisional resistance to flow. Flow regulator consist of a flow meter, an electronic module, as well as a proportional valve. Inline sensors operate in the constant temperature anemometers mode. In this case, the electrical thermal resist and the measuring resistance are adjusted to a constant temperature differentiation. Either resistances are directly in the gas stream; and three resistances are out of it. 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 maintain a clearly specified excess temperature relative to the temperature of theliquid. Owing to the fact that the resistances are disposed at once in the channel, the instrument have superb dynamics: the time for reaction when changing a given or actual value is hundredths of a millisecond. Additionally, the sensor is almost not polluted.
