Burkert Type 8626 Mass Flow Controllers are compact devices that monitoring the mass flow of gases. They regulation the set flow velocity nonetheless of obstruction including pressure loss or temporary resistance to flow. Flow regulator include a flow meter, an electronic module, as well as a proportional valve. Inline sensors operate in the constant temperature anemometers mode. In this case, the electrical heating resistance and the measuring resistance are adjusted to a constant temperature differentiation. Either resistances are immediately in the gas stream; and three resistances are out of it. 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 sustain a clearly specified surplus temperature relative to the liquid temperature. Due to the fact that the resistances are situated directly in the channel, the apparatus 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.
