Burkert Type 8626 Mass Flow Controllers are compact devices that inspection the mass flow of gases. They regulation the set flow velocity regardless of interference for instance drop in pressure or temporary flow resistance. Flow regulator include a flow meter, an electronic module, as well as a proportional valve. Inline sensors work in the constant temperature anemometers mode. In that event, the electrical heating resistance and the measuring resistance are adjusted to a constant temperature difference. Both resistances are immediately in the gas stream; three more resistances are outside him. All resistances are combined in an electrical bridge. The first resistance is gauge the temperature of the liquid. The second, low resistance, is constantly heated to maintain an expressly specified excess temperature relative to the temperature of theliquid. Owing to the reality that the resistances are situated directly in the channel, the instrument have excellent dynamics: the response time when changing a given or actual value is hundredths of a millisecond. Additionally, the sensor is almost not polluted.
