Burkert Type 8626 Mass Flow Controllers (MFC) are compact arrangement that inspection the mass flow rate of gases. They command the set flow velocity irrespective of obstruction such as drop in pressure or temporary flow resistance. Flow controllers include a flow meter, an electronic module, and a proportional valve. Inline sensors work in the CTA mode (constant temperature anemometers). In this case, the electrical heating resistance and the measuring resistance are set to a constant temperature differentiation. Either resistances are directly in the gas stream; and three resistances are out of it. All resistances are joined in an electrical bridge. The first resistance is measures the temperature of the liquid. The second, low resistance, is heated continuously to sustain an expressly defined surplus temperature relative to the temperature of theliquid. Due to the reality that the resistances are disposed directly in the channel, the devices have splendid dynamics: the response time when modifying a given or actual value is hundredths of a millisecond. In addition, the sensor is almost not contaminated.
