Burkert Type 8626 Mass Flow Controllers are compact devices that monitoring the mass flow rate of gases. They regulation the set flow velocity irrespective of obstruction such as pressure loss or temporary flow resistance. Flow controllers include a flow meter, an electronic module, as well as a proportional valve. Inline sensors operate in the CTA mode (constant temperature anemometers). In that event, the electrical heating resistance and the measuring resistance are adjusted to a constant temperature differentiation. Either resistances are immediately in the gas stream; three more resistances are outside him. All resistances are joined 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 maintain an expressly defined excess temperature relative to the temperature of theliquid. Owing to the fact that the resistances are located straight away in the channel, the apparatus have splendid dynamics: the time for reaction when changing a given or actual value is hundredths of a millisecond. In addition, the sensor is almost not contaminated.
