Mass Flow Controllers Type 8626 are compact arrangement that control the mass flow of gases. They command the set flow rate regardless of interference including pressure drops or provisional flow resistance. Flow controllers include a flow meter, an electronic module, and a proportional valve. Inline sensors operate in the constant temperature anemometers mode. In this case, the electrical thermal resistance and the measuring resistance are set to a constant temperature differentiation. Both resistances are directly in the gas stream; and three resistances are out of it. All resistances are united in an electrical bridge. The first resistance in the fluid flow measures the temperature of the liquid. The second, low resistance, is constantly heated to maintain a clearly defined excess temperature relative to the liquid temperature. Owing to the reality that the resistances are inclined straight away in the channel, the instrument have excellent dynamics: the response time when changing a given or actual value is hundredths of a millisecond. Additionally, the sensor is practically not contaminated.
