Burkert Type 8626 Mass Flow Controllers (MFC) are succinct devices that monitoring the mass flow of gases. They regulation the set flow rate irrespective of interference including drop in pressure or provisional flow resistance. Flow regulator include a flow meter, an electronic module, as well as a proportional valve. Inline sensors work in the constant temperature anemometers mode. In this case, the electrical thermal resist and the measuring resistance are set to a constant temperature differentiation. Both resistances are immediately in the gas stream; and three resistances are out of it. 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 sustain an expressly defined excess temperature relative to the temperature of thefluid. Due to the fact that the resistances are located at once 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.
