Burkert Type 8626 Mass Flow Controllers are succinct arrangement that control the mass flow rate of gases. They regulation the set flow rate irrespective of hurdle for example pressure drops or provisional flow resistance. Flow controllers consist of a flow meter, an electronic module, as well as a proportional valve. Inline sensors operate in the CTA mode (constant temperature anemometers). In this case, the electrical thermal resistance and the measuring resistance are set to a constant temperature difference. Both resistances are directly in the gas stream; three more resistances are outside him. 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 excess temperature relative to the fluid temperature. Owing to the reality that the resistances are disposed straight away in the channel, the devices 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.
