Burkert Type 8626 Mass Flow Controllers (MFC) are succinct devices that control the mass flow rate of gases. They control the set flow velocity oblivious of obstruction for example drop in pressure or temporary resistance to flow. Flow controllers include a flow meter, an electronic module, and a proportional valve. Inline sensors work 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; and three resistances are out of it. All resistances are combined in an electric bridge. The first resistance is gauge the temperature of the liquid. The second, low resistance, is heated continuously to maintain an expressly specified surplus temperature relative to the temperature of theliquid. Owing to the fact that the resistances are inclined straight away in the channel, the devices have splendid dynamics: the time for reaction when modifying a given or actual value is hundredths of a millisecond. Additionally, the sensor is practically not contaminated.
