Mass Flow Controllers Type 8626 are compact arrangement that inspection the mass flow rate of gases. They control the set flow velocity irrespective of hurdle for instance pressure loss or temporary flow resistance. Flow regulator consist of a flow meter, an electronic module, and a proportional valve. Inline sensors operate in the constant temperature anemometers mode. In that event, the electrical thermal resist and the measuring resistance are set to a constant temperature difference. Both resistances are directly in the gas stream; three more resistances are outside him. All resistances are united in an electrical bridge. The first resistance is measures the temperature of the liquid. The second, low resistance, is constantly heated to maintain a clearly specified excess temperature relative to the temperature of theliquid. Due to the reality that the resistances are disposed straight away in the channel, the apparatus have superb dynamics: the time for reaction when modifying a given or actual value is hundredths of a millisecond. Additionally, the sensor is practically not contaminated.
