Mass Flow Controllers Type 8626 are compact arrangement that inspection the mass flow rate of gases. They command the set flow rate regardless of interference such as drop in pressure or interim resistance to flow. Flow controllers include a flow meter, an electronic module, and 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 adjusted to a constant temperature differentiation. Either resistances are directly in the gas stream; and three resistances are out of it. All resistances are combined in an electrical bridge. The first resistance is gauge the temperature of the liquid. The second, low resistance, is constantly heated to maintain a clearly specified excess temperature relative to the temperature of thefluid. Due to the reality that the resistances are situated at once in the channel, the instrument have splendid dynamics: the response time when modifying a given or actual value is hundredths of a millisecond. Additionally, the sensor is practically not contaminated.
