Burkert Type 8626 Mass Flow Controllers (MFC) are compact devices that monitoring the mass flow rate of gases. They regulation the set flow velocity nonetheless of interference for instance drop in pressure or temporary resistance to flow. Flow regulator consist of 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 directly in the gas stream; and three resistances are out of it. All resistances are combined in an electric bridge. The first resistance is measures the temperature of the liquid. The second, low resistance, is constantly heated to maintain a clearly specified surplus temperature relative to the liquid temperature. Due to the fact that the resistances are located directly in the channel, the apparatus have superb dynamics: the time for reaction when modifying a given or actual value is hundredths of a millisecond. Additionally, the sensor is almost not contaminated.
