Burkert Type 8626 Mass Flow Controllers are succinct devices that monitoring the mass flow rate of gases. They control the set flow rate irrespective of hurdle for instance drop in pressure or provisional resistance to flow. Flow controllers consist of a flow meter, an electronic module, as well as a proportional valve. Inline sensors function in the constant temperature anemometers mode. In this case, the electrical heating resistance and the measuring resistance are set 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 electrical bridge. The first resistance in the fluid flow measures the temperature of the liquid. The second, low resistance, is heated continuously to maintain a clearly defined surplus temperature relative to the temperature of theliquid. Due to the fact that the resistances are situated at once in the channel, the instrument have splendid dynamics: the time for reaction when changing a given or actual value is hundredths of a millisecond. In addition, the sensor is almost not contaminated.
