Burkert Type 8626 Mass Flow Controllers are succinct arrangement that monitoring the mass flow of gases. They command the set flow velocity regardless of obstruction for example drop in pressure or provisional resistance to flow. Flow controllers 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 difference. Both resistances are immediately 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 heated continuously to maintain an expressly specified excess temperature relative to the temperature of thefluid. Due to the reality that the resistances are located at once in the channel, the instrument 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.
