Burkert Type 8626 Mass Flow Controllers (MFC) are succinct arrangement that control the mass flow of gases. They command the set flow rate 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 operate in the CTA mode (constant temperature anemometers). In that event, the electrical heating resistance and the measuring resistance are set to a constant temperature difference. Either resistances are immediately in the gas stream; three more resistances are outside him. All resistances are united in an electrical bridge. The first resistance is gauge the temperature of the liquid. The second, low resistance, is heated continuously to sustain an expressly specified surplus temperature relative to the liquid temperature. Due to the reality that the resistances are situated directly in the channel, the apparatus have splendid dynamics: the time for reaction when modifying a given or actual value is hundredths of a millisecond. Additionally, the sensor is almost not contaminated.
