Burkert Type 8626 Mass Flow Controllers are compact devices that inspection the mass flow rate of gases. They control the set flow velocity irrespective of hurdle for example drop in pressure or temporary resistance to flow. Flow regulator include a flow meter, an electronic module, and a proportional valve. Inline sensors work in the CTA mode (constant temperature anemometers). In this case, the electrical thermal resist and the measuring resistance are set 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 electrical bridge. The first resistance in the fluid flow measures the temperature of the liquid. The second, low resistance, is heated continuously to sustain a clearly specified surplus temperature relative to the temperature of theliquid. Due to the reality that the resistances are located at once in the channel, the apparatus have excellent dynamics: the response time when altering a given or actual value is hundredths of a millisecond. In addition, the sensor is almost not contaminated.
