Mass Flow Controllers Type 8626 are succinct devices that control the mass flow rate of gases. They regulation the set flow velocity oblivious of hurdle for example pressure drops or temporary flow resistance. Flow controllers consist of a flow meter, an electronic module, as well as a proportional valve. Inline sensors operate in the constant temperature anemometers mode. In this case, the electrical thermal resist and the measuring resistance are adjusted to a constant temperature difference. Either resistances are directly in the gas stream; three more resistances are outside him. 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 sustain a clearly defined surplus temperature relative to the temperature of theliquid. Owing to the reality that the resistances are disposed straight away in the channel, the apparatus have excellent dynamics: the time for reaction when changing a given or actual value is hundredths of a millisecond. In addition, the sensor is practically not polluted.
