Mass Flow Controllers Type 8626 are succinct devices that control the mass flow rate of gases. They command the set flow velocity irrespective of obstruction for instance drop in pressure or provisional resistance to flow. Flow regulator consist of a flow meter, an electronic module, as well as a proportional valve. Inline sensors operate in the CTA mode (constant temperature anemometers). In that event, the electrical heating resist 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 united in an electric bridge. The first resistance is measures the temperature of the fluid. The second, low resistance, is heated continuously to sustain an expressly specified surplus temperature relative to the temperature of thefluid. Due to the fact that the resistances are located directly in the channel, the devices have splendid dynamics: the time for reaction when changing a given or actual value is hundredths of a millisecond. In addition, the sensor is almost not polluted.
