Mass Flow Controllers Type 8626 are compact devices that control the mass flow rate of gases. They command the set flow velocity nonetheless of obstruction for example drop in pressure or provisional flow resistance. Flow controllers include a flow meter, an electronic module, as well as a proportional valve. Inline sensors work in the CTA mode (constant temperature anemometers). In this case, the electrical thermal resistance and the measuring resistance are adjusted to a constant temperature difference. Either resistances are immediately in the gas stream; three more resistances are outside him. All resistances are combined in an electric bridge. The first resistance is measures the temperature of the liquid. The second, low resistance, is constantly heated to sustain an expressly defined surplus temperature relative to the temperature of thefluid. Due to the reality that the resistances are disposed straight away in the channel, the apparatus have superb dynamics: the response time when altering a given or actual value is hundredths of a millisecond. In addition, the sensor is almost not polluted.
