Mass Flow Controllers Type 8626 are compact devices that monitoring the mass flow of gases. They regulation the set flow rate irrespective of hurdle such as drop in pressure or temporary flow resistance. Flow regulator consist of a flow meter, an electronic module, and a proportional valve. Inline sensors work in the CTA mode (constant temperature anemometers). In that event, the electrical thermal resistance and the measuring resistance are adjusted to a constant temperature differentiation. Either resistances are immediately in the gas stream; three more resistances are outside him. All resistances are joined in an electrical 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 thefluid. Owing to the reality that the resistances are disposed directly in the channel, the apparatus have superb dynamics: the response time when changing a given or actual value is hundredths of a millisecond. Additionally, the sensor is practically not polluted.
