Mass Flow Controllers Type 8626 are succinct arrangement that control the mass flow of gases. They control the set flow rate regardless of hurdle for example drop in pressure or provisional resistance to flow. Flow regulator consist of a flow meter, an electronic module, and a proportional valve. Inline sensors work in the constant temperature anemometers mode. In this case, the electrical thermal resist and the measuring resistance are set to a constant temperature difference. Both 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 fluid. The second, low resistance, is heated continuously to sustain a clearly specified surplus temperature relative to the fluid temperature. Due to the reality that the resistances are situated directly in the channel, the instrument have excellent dynamics: the response time when altering a given or actual value is hundredths of a millisecond. Additionally, the sensor is practically not polluted.
