Mass Flow Controllers Type 8626 are succinct arrangement that monitoring the mass flow rate of gases. They command the set flow rate oblivious of interference including drop in pressure or interim flow resistance. Flow regulator consist of a flow meter, an electronic module, as well as a proportional valve. Inline sensors function in the CTA mode (constant temperature anemometers). In this case, the electrical heating resist and the measuring resistance are adjusted to a constant temperature differentiation. Either resistances are directly in the gas stream; and three resistances are out of it. All resistances are combined in an electrical bridge. The first resistance in the fluid flow measures the temperature of the liquid. The second, low resistance, is constantly heated to sustain an expressly specified excess temperature relative to the fluid temperature. Owing to the reality that the resistances are situated directly in the channel, the devices have superb dynamics: the time for reaction when changing a given or actual value is hundredths of a millisecond. In addition, the sensor is practically not contaminated.
