Mass Flow Controllers Type 8626 are compact devices that monitoring the mass flow of gases. They control the set flow rate nonetheless of hurdle such as pressure loss or provisional resistance to flow. Flow controllers consist of a flow meter, an electronic module, as well as 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 difference. Both resistances are directly 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 an expressly specified surplus temperature relative to the temperature of theliquid. Owing to the reality that the resistances are disposed at once in the channel, the apparatus have splendid dynamics: the time for reaction when changing a given or actual value is hundredths of a millisecond. Additionally, the sensor is almost not contaminated.
