Burkert Type 8626 Mass Flow Controllers are compact arrangement that control the mass flow of gases. They command the set flow velocity irrespective of interference including drop in pressure or provisional resistance to flow. Flow controllers consist of a flow meter, an electronic module, and a proportional valve. Inline sensors operate in the CTA mode (constant temperature anemometers). In that event, the electrical thermal resist and the measuring resistance are set 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 electric bridge. The first resistance in the fluid flow measures the temperature of the liquid. The second, low resistance, is constantly heated to sustain a clearly specified excess temperature relative to the liquid temperature. Owing to the fact that the resistances are located directly in the channel, the devices have splendid dynamics: the response time when altering a given or actual value is hundredths of a millisecond. Additionally, the sensor is almost not contaminated.
