Burkert Type 8626 Mass Flow Controllers are compact devices that control the mass flow of gases. They regulation the set flow velocity irrespective 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 function in the CTA mode (constant temperature anemometers). In that event, the electrical thermal resist 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 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 maintain a clearly defined surplus temperature relative to the liquid temperature. Owing to the reality that the resistances are situated straight away in the channel, the apparatus have excellent dynamics: the response time when modifying a given or actual value is hundredths of a millisecond. Additionally, the sensor is almost not contaminated.
