Mass Flow Controllers Type 8626 are compact devices that monitoring the mass flow rate of gases. They command the set flow rate nonetheless of hurdle for instance drop in pressure or temporary 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 heating resist and the measuring resistance are set to a constant temperature difference. Both resistances are immediately in the gas stream; three more resistances are outside him. All resistances are united 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 maintain an expressly specified excess temperature relative to the liquid temperature. Due to the fact that the resistances are located at once in the channel, the apparatus have splendid dynamics: the response time when altering a given or actual value is hundredths of a millisecond. In addition, the sensor is almost not contaminated.
