Burkert Type 8626 Mass Flow Controllers are succinct devices that monitoring the mass flow rate of gases. They command the set flow velocity regardless of hurdle for example pressure loss or temporary resistance to flow. Flow controllers consist of a flow meter, an electronic module, and a proportional valve. Inline sensors function in the CTA mode (constant temperature anemometers). In this case, the electrical thermal resistance and the measuring resistance are adjusted to a constant temperature differentiation. Both resistances are directly in the gas stream; three more resistances are outside him. All resistances are joined 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 temperature of thefluid. Owing to the fact that the resistances are inclined straight away in the channel, the devices have excellent dynamics: the time for reaction when modifying a given or actual value is hundredths of a millisecond. In addition, the sensor is almost not contaminated.
