Mass Flow Controllers Type 8626 are compact arrangement that control the mass flow rate of gases. They command the set flow velocity regardless of interference including drop in pressure or interim resistance to flow. Flow regulator include a flow meter, an electronic module, as well as 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 differentiation. Both resistances are directly in the gas stream; and three resistances are out of it. All resistances are united in an electric bridge. The first resistance in the fluid flow measures the temperature of the liquid. The second, low resistance, is heated continuously to maintain a clearly specified surplus temperature relative to the liquid temperature. Due to the reality that the resistances are disposed straight away in the channel, the devices 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.
