Burkert Type 8626 Mass Flow Controllers are compact arrangement that control the mass flow of gases. They regulation the set flow rate irrespective of hurdle for example pressure drops or temporary flow resistance. Flow controllers consist of 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 thermal 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 united in an electrical bridge. The first resistance in the fluid flow measures the temperature of the liquid. The second, low resistance, is heated continuously to maintain an expressly defined surplus temperature relative to the liquid temperature. Due to the reality that the resistances are inclined at once in the channel, the instrument have splendid dynamics: the response time when modifying a given or actual value is hundredths of a millisecond. In addition, the sensor is practically not contaminated.
