Burkert Type 8626 Mass Flow Controllers are compact arrangement that control the mass flow rate of gases. They regulation the set flow velocity regardless of obstruction including drop in pressure or interim resistance to flow. Flow controllers include a flow meter, an electronic module, as well as a proportional valve. Inline sensors operate in the constant temperature anemometers mode. In this case, the electrical thermal resistance and the measuring resistance are adjusted to a constant temperature difference. Either resistances are directly in the gas stream; and three resistances are out of it. All resistances are united in an electrical bridge. The first resistance is gauge the temperature of the liquid. The second, low resistance, is heated continuously to sustain a clearly defined surplus temperature relative to the liquid temperature. Owing to the fact that the resistances are situated straight away in the channel, the devices have superb dynamics: the response time when modifying a given or actual value is hundredths of a millisecond. In addition, the sensor is practically not polluted.
