Burkert Type 8626 Mass Flow Controllers are succinct devices that control the mass flow rate of gases. They regulation the set flow rate oblivious of hurdle including drop in pressure or provisional resistance to flow. Flow regulator consist of a flow meter, an electronic module, as well as a proportional valve. Inline sensors function in the CTA mode (constant temperature anemometers). In this case, the electrical thermal resist 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 combined in an electric bridge. The first resistance is gauge the temperature of the liquid. The second, low resistance, is heated continuously to sustain a clearly specified excess temperature relative to the temperature of theliquid. Owing to the fact that the resistances are situated directly in the channel, the instrument have splendid dynamics: the time for reaction when modifying a given or actual value is hundredths of a millisecond. In addition, the sensor is almost not contaminated.
