Mass Flow Controllers Type 8626 are succinct arrangement that monitoring the mass flow rate of gases. They control the set flow rate regardless of interference for example drop in pressure or interim resistance to flow. Flow regulator include a flow meter, an electronic module, and a proportional valve. Inline sensors operate in the CTA mode (constant temperature anemometers). In this case, the electrical heating resist and the measuring resistance are adjusted to a constant temperature difference. Either resistances are immediately in the gas stream; and three resistances are out of it. 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 constantly heated to maintain an expressly specified excess temperature relative to the temperature of thefluid. Owing to the reality that the resistances are situated at once in the channel, the instrument have superb dynamics: the response time when altering a given or actual value is hundredths of a millisecond. In addition, the sensor is practically not contaminated.
