Burkert Type 8626 Mass Flow Controllers (MFC) are compact devices that inspection the mass flow of gases. They command the set flow rate regardless of interference for example pressure loss or temporary flow resistance. 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 heating resist and the measuring resistance are set to a constant temperature difference. Either 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 measures the temperature of the liquid. The second, low resistance, is constantly heated to sustain a clearly defined surplus temperature relative to the fluid temperature. Due to the fact that the resistances are disposed straight away in the channel, the apparatus have excellent dynamics: the time for reaction when altering a given or actual value is hundredths of a millisecond. In addition, the sensor is practically not contaminated.
