Burkert Type 8626 Mass Flow Controllers (MFC) are succinct devices that monitoring the mass flow of gases. They regulation the set flow rate regardless of obstruction including drop in pressure or interim resistance to flow. Flow controllers include a flow meter, an electronic module, as well as a proportional valve. Inline sensors work in the CTA mode (constant temperature anemometers). 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 combined in an electric 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 surplus temperature relative to the liquid temperature. Owing to the fact that the resistances are situated directly in the channel, the devices have excellent dynamics: the response time when changing a given or actual value is hundredths of a millisecond. In addition, the sensor is almost not polluted.
